Ha! Funnily enough I just responded to a different comment along these same lines: that's the beauty of the fediverse. If a community of moaners exist, they could have their own instance. Or in the case of Lemmy (and the very theoretical Habitat), their own categories that other users can tune out from. I think you're going to have places in which moderation is a success and places in which it isn't. Anything that isn't moderated appropriately and gets taken down as a result of something actually illegal won't affect the communities that are appropriately moderated, because it can all be separated. It seems to be working well enough for Lemmy.
