To be clear, not talking about this community, obviously 😛.
What's the point of writing down rules, if mods just do what they want? But I suppose that's the risk you take when you call someone a liar in a small community; they might be a mod.
Edit: I'm not trying to say that mods suck, they perform a useful and often thankless job. Just that it can be difficult for small communities to get a healthy number of good mods, which can become a problem.
I really, really suspect that the big Lemmy instances are being run by Reddit admins or spooks or some-such. They’re moderating their instances in the exact same way Reddit did minus the profiteering. The censorship is the exact same.
It's just the reality of online content moderation. The good mods/admins are people who are passionate about a topic and want to provide a space for discussion and community building. When it comes to the "power mods" or whatever, like those we saw on reddit who moderated 100+ subs, they're just in it to stroke their own egos.
