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.

The example that introduced me to federation was like an instance getting overrun with Nazis, and everyone deciding to just cut that instance loose; let it float alone as "the Nazi instance" that nobody has to interact with.
I thought that stuff like bad actors and assholes was one of the main reasons for the idea of federation, really surprised how many people thought differently
