In the graph above I’ve arranged the 28 Threadiverse instances with at least 200 monthly active users (MAU)—orange instances running Lemmy, green Piefed, and red Mbin—on the basis of which instances they defederate.
Each instance has its MAU count listed below it, sourced from the latest MAU figures at Fediverse Observer, with adjustments made to the totals for Piefed (due to undercounting by outdated instances, as noted here; I used @Vicinus@piefed.zip’s suggested estimate of 7,200 Piefed users) and Mbin (due to tardigram.com having a duplicate listing).
After adjustments, there are an estimated 43,287 monthly active Threadiverse users (35,184+7,200+903), of whom 87.84% are on the 28 largest instances. The percentages listed alongside the MAU figures correspond to each instance’s share of the total MAU count.
Defederation data was sourced from Federation Checker. The tool doesn’t support Mbin instances, so I left fedia.io in its own category. If any defederations are missing, feel free to let me know. Ideally such a chart should also include community blocks to better illustrate which instances block what, but that data doesn’t appear to be as easily searchable.
I also noticed cases of some instances being listed as being defederated by another instance, despite not appearing on the defederation list for that instance (i.e. reddthat.com and lemmygrad.ml are listed as being mutually blocked, despite neither having the other on their block lists). In testing that federation, I noticed that !wholesome@reddthat.com did not federate to Lemmygrad while !memes@reddthat.com did, so clarification on that matter would be helpful.
While I’ll update my generalized chart as needed to correct errors, perhaps at some point an automated federation mapping tool similar to the one feddit.de formerly hosted could be developed to more completely illustrate instance federation.
Very proud of lemmy.zip! Joined very early on cause the name sounded cool lol, and apparently a lot of others also did. If i remember right we had a vote on defederations and the only major one to happen(or maybe the only one, idk) was exploding heads which was a nazi instance with CSAM on it so that was obvious, even that was mainly cause of the CSAM. I really like the approach of users being able to block instances and communities rather than the instance deciding for me. I still have ml and hexbear blocked tho cause they banned me after i stood up for trans rights or something lol
I’m feeling the same way. I’ve bounced around a few places since joining. I started on midwest.social which was great for a while, but I think the instance grew more than the dev could keep up with. I started seeing connectivity issues and problems displaying content so I reluctantly migrated to .world to see what joining the largest instance would be like. The technical issues went away but I couldn’t figure out why I could no longer see /c/piracy until I realized that they’re a bunch of pushovers that defederated from dbzer0 based on some liability bogeyman. So I found myself on Lemmy.zip where I can police my own content and have no technical issues.
.zip and Demogodrick definitely cool.
I also lucked out by joining here just because I couldnt join more popular instances at the time. Happy that I landed here
Well that’s a confusing graph.
Yeah I cant understand it at all.
Since defederating is essentially an explicit block list and is directional, my assumption is that the groups that are circled have defederated from the things they’re pointing at. I could be wrong.
Map needs a key/legend.
The red circled stuff seems to be only one possible option, but isn’t visually very distinct, and the red circle shouldn’t be broken like that, just make sure the lines are all visible.
Apologies for the confusion; didn’t want to make it overly cluttered, but in retrospect I see that a legend would have been useful. I’ll incorporate suggestions in a revision.
Yeah, as someone who is struggling to understand the concept of federation…this doesn’t help me at all.
I guess what its saying, if you’re on lemmy.world, you can’t access content on lemmy.zip?
If I’m reading it correctly, lemmy.world cut ties from lemmygrad.ml and hexbear.net while hexbear.net and beehaw.org cut ties with lemmy.world. lemmy.zip appears to be connected to everyone.
Why would they do that? I’m unaware of internal issues in Lemmy at this point?
Ideological differences. Lemmy.world is liberal, while lemmygrad and hexbear are hardcore communists (aka tankies).
The ones at the bottom that are below the None category aren’t defederated from anyone, so they can access every instance.
What’s with feddit.org?
There are a lot of threads here about this. Feddit.org wants to keep in line with local laws in their jurisdiction, dbzero thinks that this is a pro-zionist stand and genocide-denial.
The admins of feddit.org are afraid of german police coming for their servers and therefore ban content that is possibly illegal in germany quite liberally. Since german courts are sometimes weird this includes some Pro-Palestine content that could be interpreted as Anti-Israel (e.g. the chant “From the river to the sea…”). That topic in particular pissed of the dbzero community which then defereated feddit.org for being “Zionists”.
I mean, it is kinda. Anticipatory obedience makes you complicit.
Yup. Anticipatory obedience isn’t the way to go!
Well, if you have to personally liable for the shit a bunch of internet strangers say, you might think differently. That is one boon of being a mega-corp. You are somewhat immune to SLAPP-lawsuits and the like.
Uhm, this was translated right? “vorauseilender Gehorsam”
Does that mean that discuss does not federate with lmmy.ml, lemmygrad, programming.dev and hexbears?
We might read the diagram differently, but I only see a defederation with lemmygrad.
Correct 👍
No, discuss is only in the blue box, which’s arrow points to lemmygrad, so they defederated from them.
You must not read this Graph like a Venn diagram
Wow, infosec.pub is based!
I really like this but I can not figure it out. Would you be willing to make the data available?
The MAU numbers for instances were sourced from Fediverse Observer and calculated as a percentage of 43,287 for the percentages, but here’s a table of the defederation data:
Lemmy Instance Defederates lemmy.world Hexbear, Lemmygrad sh.itjust.works Beehaw, Hexbear, Lemmygrad lemmy.zip N/A lemmy.ml fedinsfw.app feddit.org fedinsfw.app, Hexbear, Lemmygrad hexbear.net lemmy.world lemmy.dbzer0.com Lemmygrad, Feddit.org lemmy.ca Hexbear, Lemmygrad lemmy.blahaj.zone fedinsfw.app, Hexbear, Lemmygrad programming.dev Hexbear discuss.tchncs.de Lemmygrad sopuli.xyz fedinsfw.app, Hexbear, Lemmygrad lemmygrad.ml fedinsfw.app lemmy.today N/A slrpnk.net Hexbear, Lemmygrad feddit.uk N/A infosec.pub fedinsfw.app, Hexbear, Lemmygrad, Lemmy.ml reddthat.com N/A jlai.lu Lemmygrad beehaw.org sh.itjust.works, lemmy.world, Lemmygrad, Hexbear pawb.social Hexbear, Lemmygrad thelemmy.club N/A feddit.nl N/A Piefed Instance Defederates fedinsfw.app Hexbear, Lemmygrad piefed.social Hexbear, Lemmygrad piefed.ca Hexbear, Lemmygrad piefed.zip N/A Mbin Instance Defederates fedia.io ? What the hell are Hexbear and Lemmygrad and what did they do that everyone’s blocking them?
To add an annecdote, hexbear has this handy link to an image: (nsfw) https://hexbear.net/PPB
Ask yourself why a discussion platform might keep this image quick-link and you may understand why everyone defederates from them.
Lammygrad are Marxist Leninist, Hexbear are dirtbag leftists. That makes them the natural enemies of center-left and centrist instances like .world.
In my opinion it comes down to a disagreement over capitalism. One side wants to destroy it, the other side wants to moderate it.
also worth noting that I’d have all the data in the Lemmyverse.net data, I could probably build a page that shows something similar to this graph.
What’s the beef between beehaw and lemmy.world?
Not so much beef as in beehaw could not manage the torrent of content coming their way from world
According to beehaw there’s no beef, it’s just too many users for them to effectively moderate
Block the “default”. That’s actually pretty clever. Not because you dislike those people, but because it’s the default and requires extra effort to not be a part of.
The beehaw.org/sh.itjust.works defederation is really one-way. Beehaw defederated from us after some exceptionally bad trolls were operating from sh.itjust.works in 2023. IIRC, they requested that we also defederate from them to really make sure the split was made. We honored their request.
We would happily reconnect if Beehaw decided they want to federate with us again. If not, then that’s fine; they have a right to associate with whomever they like.
I believe infosec.pub temporarily defederated from us around the same time for the same reason. It was a rough time.
I’ll adjust the graph by the next version to account for it as an exception.
If you want to complicate the graph further, I believe hexbear federates using an allow list. Blahaj, lemmy.ca, and sh.itjust.works are not on the allow list, so they are effectively defederated. I haven’t looked further to see which other large instances may be affected.
Graph is very big resolution-wise, it lags. Do you have a slightly smaller one?
Here’s a version exported at 150 DPI instead of 300:

Thanks, that works! :3
Things that pop out to me:
- The Internet was made for porn, both in users and less defederating.
- The main blocks really are mostly the Triad (grad, hexbear and ml) which I get. I personally don’t mind tankies despite the instance I’m on, but they can sometimes echo Russian propaganda that’s demonstrably false. Communism as a concept is ok, though.
The Beehaw thing predates me, I heard they’re nice people, though. I also agree with the sentiment that more fringe groups and random porn might scare away newbies, so I get why things are the way they are.
(Sorry, couldn’t resist)
Our instance deferated fedinsfw because of the adult porn pretending to be child porn pretending to be adult porn. According to Australian law, fake child porn is legally considered child porn, and also our users think it’s gross.
I say, I really don’t get why so many people stay over on Reddit.
This might be a micro version of the actual future internet, where we walk away from the global model and split it into ideological countries who believe the best way forward is to stop talking to the other group.
We’ve come a long way from drawing artificial lines on maps.
I can understand people staying on Reddit more than those staying on Twitter to be honest.
At least spez hasn’t gone full nazi yet, or provided tools for generating pedophilia.
Both of which people seem to be perfectly fine with. So it doesn’t surprise me they’re fine with Reddit too.
At least spez hasn’t gone full nazi yet

The fediverse is great if you fall into the like 5 interests that are pretty well represented here.
But if the communities you wanna engage with aren’t really active enough for potential posters to not just forget they exist, or you don’t really want to be on a platform where 75% of the front page is news or memes about the state of the world politically, its not neccisarily a great replacement to reddit
For me it happens to cover enough of my bases, but I can get why it wouldn’t for many people.
I’ve said this a number of times over the past couple days, but if there’s an instance for mirroring subreddits, where niche subreddits that don’t have an equivalent here yet basically get a carbon copy and a repost bot to stock them with relevant stuff from over there, that could fill in some of those gaps and make the fediverse a more attractive alternative.
It won’t have the same level of engagement right away, but it will provide a place for that engagement to occur, and as more people start using it it will create a network effect. As things stand now, we’re missing a lot of those niche communities.
It really is pretty dead outside the main subjects. I have noone to talk about the latest episode of My Adventures with Superman. Did they now just leave the other universe with Clark dead? That sucks.
Just like in real life, one must grow and sometimes create the communities they want to be apart of.
Difficult when people here only like 5 things and they shun everything that is not those 5 things.
While thats true, if my friend whose biggest interests are science informed dog training and animal genetics joins the threadiverse there are not enough people here who genuinely really care about those subjects to actually sustain any of the social connection she’s looking for around them.
If my friend who’s super into basketball and competitive league of legends join she’d have at least a couple people to talk to, but its fundamentally not what she’s looking for to talk to exactly 3 other people who care about the thing she’s into.
I try to remember that as much as I love the fediverse and feel at home here, it has real limitations for lots of people, and its okay if its not in a state they can go enjoy very easily. This is a space that I am passionate about and want to contribute to. I don’t expect everyone to do labor to invest in a space that isnt their passion just to chat with folks when they have the ability to chat with folks somewhere else, even if that place has bigger picture downsides or harms associated with it.
You can still choose one that talks to everybody else. In fact, this graphic might be a nice tool for new users who want advice beyond “Just choose any instance, it doesn’t matter” or “Just use lemmy.world”.
I don’t know if this is better or worse. I do like the selectivity of it, though, where you’re free to join or privately defederate instances
I say, I really don’t get why so many people stay over on Reddit.
This place fuckin sucks man? It’s pretty much reddit for left wing progressives who specifically care about left wing American* politics, linux, and not much else
That’s slander!
We also like Star Trek!
While it would be nice if there were more activity, when the alternative is the ever-enshittifying Reddit, our best option is to contribute what we can here, be as welcoming as possible to new users, and block any content that isn’t interesting to achieve a personalized feed of one’s preferred content.
You can always post eco-fascist Australian memes if that’s more your thing
@Zedstrian@sopuli.xyz this is what I mean, cunts everywhere in this place, why would I encourage anyone to come here?
Banned 1 day for being disrespectful. Next one is a perma.
Unfortunately there are too many people here who would rather be brash and rude at the hint of any disagreement, rather than discussing civilly and promoting a healthy community that is not an echo chamber.
My best advice is to just block people who you find rude to make the remainder slightly less rude on average.
I’m a cunt? I’m just encouraging you to follow your dreams.
You can even post anti-linux memes with that one other guy.
Kinda eye-opening, thx for making the chart. I hadn’t realized it had gotten this bad. In my opinion, defederation should only ever be used to combat spam, not because of ideological differences or disputes between individuals.
One of the most common tips for people looking to switch over from Reddit has been that the instance you choose doesn’t really matter. But it clearly does. Choose the “wrong” instance and you may suddenly find yourself cut off from a sizable portion of other users because someone else decided they know better than you what you should and shouldn’t see.
I’m lucky to be on an instance that has “only” defederated one instance in this chart (lemmygrad.ml). I don’t really follow the drama around here, so I have no idea why that instance is banned. All I see is that there are 558 active users I’ll never be able to interact with just because someone I don’t personally know (my instance admin) made that decision at some point.
Wasn’t there just a big drama because some app developer built-in their own opinionated blocklist into their app or something? How is this any different?
My point being, why not leave these kinds of drastic decisions to individual users, who can and should block whoever they want, instead of dividing threadiverse into silos at the instance level?
This is what organic growth looks like. It spreads in fits and starts, bits of it clump together and pile up, pieces of it separate and take on life of their own or die. When part of it rots (hexbear) the larger organism cuts it off to limit the spread of disease.
Lemmy (and more generally, ActivityPub) is growing, not like a rose bush, but like a field of grass. Some pieces of it are blooming, some pieces of it are dying, some pieces are adapting to different environments, but the spread is inexorable and the horizon unlimited.
If you want to see what the field is like on the other side of that hill, well it won’t just come to you, you’ll have to get up and go to it.
Many fantastic instances do exactly that.
But in answer to your question, you may want to research The Intolerance Paradox. In short, when people refuse to follow the rules it kinda becomes spam. Even if you were okay with CSAM or pictures of pigs actively showing the poop falling out of their anuses (sadly, I bet you think I am being hyperbolic here? nope, this is kinda Hexbear’s major schtick), the fact remains that it scares away newcomers.
I will note that if you self-host your own instance then you have perfect control over every aspect of your experience, being able to fine-tune it to perfectly suit your precise needs. Otherwise you will want to choose an instance provider that aligns with whatever your needs are. Some people will choose one of the instances that defederates from almost nothing, while others actually want an experience that is more what they are used to and would expect coming over from the overly bot-modded Reddit, i.e. they want (even outright demand) that censorship be done for them.
This is why the instance pickers need to carefully explain what each instance is about, since there is not just one audience with a single set of needs & expectations.
Yeah, I get your argument, and obviously it’s good to have instances with different federation policies. It’s just that when big instances like the ones in this chart start swinging the defederation hammer around, I worry that some (or many) users end up disconnected from users and communities without ever realizing it or agreeing with the decision.
Have you ever tried to organize a fun game night with friends but two of them just can’t get along, ruining the whole thing? That’s kinda the feeling I get from this.
Okay but… have you ever tried to force your group to get together despite those two being unable to get along? e.g. Russia vs. Ukraine? China vs. Taiwan? Israel vs. Palestine? USA vs. a neighbor with oil?
Whether one side (e.g. Ukraine) can “get along with” the other side there (e.g. Russia) depends a LOT on whether they are able to agree to follow some shared rules (e.g. to not murder the other side). These are not mere political differences in the sense of left vs. right, but rather those who are proud to remain ungovernable (while seemingly not understanding what that phrase originally was intended to mean) vs. those who would rather nope out entirely than exist side-by-side with them.
Please also note that Lemmy’s block tools are so misleadingly misnamed as to be almost worthy of the moniker of calling it disinformation. What “blocking an instance” does is to:
- Mute communities on that instance from the user, preventing discoverability and blocking that content from showing in your personal feed, including when browsing All
What that so-called “blocking” does NOT do:
- Hide content from those users submitted to communities on remote instances
- Prevent those users from being able to reply to, famously including vote brigading on, your own content
- Prevent those users from sending you DMs, which at first were not allowed to trigger notifications, but the Lemmy devs reversed that decision and now these “blocked users” can trigger notifications - which bc of the “style” preferred by people on those instances, can continue for WEEKS and WEEKS after you so much as reply to a post that you encountered on All, without having read the sidebar and so not knowing that this style differs from what you are used to
Besides, even if insurance blocking actually worked, it would still do nothing to not showcase the content for an anonymous guest account or a newly created account, i.e. it does nothing to help others deal with “the situation”, only yourself. Which is especially notable when people access Lemmy’s content from apps like Voyager that by default does not show the instance name, thereby treating all content from all instances as being equal. However, I would argue that e.g. Poland does not fear attack from all nations equally - does Poland want to be on guard against Taiwan? Or North or South Korea? What about Russia?
Defederation is a blunt tool, but is virtually the only one offered by the Lemmy devs. When the software is made more robust to offer some other alternative… then this issue can be revisited at that time.
Also, you are free at any to self-host your own instance. But to tell Ukraine and Russia that they must get along… or else what? I am saying that I reject the underlying premise of your argument. “People getting along” should not be the ultimate goal of the Threadiverse. A better goal IMHO would be “People enjoying their experiences while here”. Which for many, means blocking Hexbear - and yes, for some it means NOT blocking it - and therefore since the answer is neither a clear yay or nay, we are forced into preaching the controversy for every new potential member, even though that very complexity itself is often what drives others away.
Though PieFed.zip offers an intriguing and innovative compromise: upon joining the instance a user block is placed upon the Hexbear and lemmygrad instances, and a message sent to the new user about how to remove or place such blocks. This makes federation with those highly controversial instances as opt-in, as opposed to opt-out or impossible to block or not block. That’s really neat! However, that delves into a whole other can of worms on how PieFed instance blocks have problems - namely that people on the receiving end can still reply to them, though only people on the same originating instance will see those replies (or perhaps it’s worse and everyone using Lemmy will see them while everyone using PieFed will not? or perhaps something else altogether?). Also this in turn opens up an entirely new rabbit hole on top of that, where Lemmy and PieFed (and Mbin, and nodeBB, etc.) would need to agree on a set of shared practices…
In short, the technology of the Threadiverse is still quite primitive in so very many ways, despite the upcoming release of Lemmy vs. 1.0. Yes defederation is a very blunt instrument, but it’s all that we have been given to wield for the most part. But the alternative IMHO would be far worse, being forced into allowing bullies to thrive. The Paradox of Intolerance is ironic, but very real: allowing the intolerant to exist in your space, worse yet platforming and even promoting them, means that you yourself are intolerant. Fences between neighbors is the only hope the Threadiverse even has of surviving. Yes you are allowed to be sad at that fact, but it remains true nonetheless. Move past your sadness, to get to what must be done to thrive and move forward in a positive direction?
e.g. learn Rust and contribute to the code development of Lemmy!? Unfortunately, merely donating money is unlikely to help, as much of those funds go into the moderation and instance maintenance costs of the “highly controversial” Lemmy.ml, and the devs have refused to open a way to provide funding for the former independently of the latter. Or learn Python and contribute to development of PieFed? It likely won’t help with interoperability between PieFed vs. Lemmy, and both require investments of several years, but if you want to help then there is no better way. So long as the technology remains as primitive as it is now, these kinds of blunt instruments are all that are available to us - someone would need to invest the effort to provide better.
TLDR: there are extremely good reasons why things are as they are now.
Note that defederations with smaller instances (representing 12% of users) are not represented here, so there are even more defederations than what is listed here. Hopefully that will come across better with more data in the next version of the graph.
As requiring new users to implement multiple blocks off the bat can be a big ask for those still on the fence about leaving Reddit, defederating known NSFW, troll, and tankie instances can improve new user retention. For those who prefer more hands-off moderation practices, specific instances can cater to them, but I think a more tailored experience is better for users arriving from Reddit.
Idk, that is exactly how lemmy.zip does it. Fairly straight forward if you ask me.
I think the main issue is that this isn’t communicated clearly. Most people joining a random instance listed on join-lemmy.org won’t know what defederation means and they have no way of knowing that by choosing that particular instance they’ll be cut off from a certain number of other users.
I’m not so sure, I’d rather have a prepopulated blocklist that I can further configure myself, as opposed to instance level blocks that I can’t reverse.
Does the fedia federation list provide you the data you need in order to include them?
Fedia appears to require users to log in to access anything, including federation status?
deleted by creator
I thought the % underneath was the number of users who couldn’t see that instance, but I guess it’s % of the active fediverse users?
Yes; the percentage underneath an instance is its proportion of the overall Threadiverse userbase. The percentages on the large arrows are the sum of the userbases within the associated box, indicating the extent to which an instance is defederated (somewhat of an underestimation, given that 12% of users are unaccounted for).
On the one hand, I know that the long tail of smaller instances are important to the health of the fediverse, but on the other it seems like it would be fun to see my instances on the defederation flowchart and the alt text leaderboard and stuff. Plusses and minuses, I suppose.
At 152 MAU, it’ll make the cut if I expand the minimum threshold for inclusion to 150 MAU instead of 200; the limit was used to make the chart easier to plan, but I think it could be expanded incrementally.
