the thing youre missing about the fediverse.. if a community does not approve of a mod they can literally pick up and move their community to a new community or even a different instance altogether.
this has happened at least a few times.
moderation is a necessary management tool, and yes, it is certainly abused.. but the fediverse gives us the ability to tell mods to go fuck themselves.
The fact that unmoderated places attract pedophiles sharing pictures, Spambots, and trolls.
Go take a look at a random board on 8kun if you don't believe me.
It's largely unmoderated, you'll love it!!!
