The way I see it, is that the rules and aim of the instance are all written out pretty fucking clearly and people on a platform dominated by longform text don't really have an excuse for not being able to comprehend it. Like seriously, I had been using Lemmy for two days when I checked out Blåhaj, and I feel like I understood then already because it's not hard and English is my native language.
So that said, when I see people complaining about it, I think they're either fucking stupid, or they're probably these 'free speech' people that want the right to go around insulting everyone without consequences (while doing the most epic pearl clutching the moment anyone insults them).
As far as I'm concerned, moderators and admins doing exactly what is clearly fucking written in the description and rules is not power abuse.
These are the same people that think 'freedom' is dictating to others how they're allowed to live their lives, 'free speech' is deporting anyone that says something you don't like and that the preacher who gets a little too friendly with the youth group 'cares about the kids'. So assume that everything they say and claim to stand for is doublespeak.
