I still occasionally run across the odd dodgy website that tried to disable zooming (along with other oddities like trying to disable right clicking on desktop) and it feels honestly that most of these annoyances come about because some asshole in the company (the CEO, lead designer, marketer, whatever) sees any changes to their websites from the user as “ruining the experience”, disregarding the whole concept of accessibility in the modern web
I’d also argue that regardless of the server size, it takes literal seconds to explain why your account is getting banned, it’s absolutely within the realm of reason that if your system allowed automated signups that you as an admin have an obligation to not be a shitcunt and at least give a reason as to why you’re banning accounts.
