The instance seems to be mostly right wing trolls. I know defederating is unpopular but I don't think much is to be lost in this case and it can save the mods some headaches.

My experience with exploding-heads is they are mostly level headed serious users and not trolls at all. Defederating because one person had their feeling hurt is dumb and ruins the fediverse for everyone
