Defederation is the nuclear option. Until now we had removed any communities we weren't comfortable hosting, and treated users on a case-by-case basis based on how they behaved in our communities, which worked for a while but became untenable.

When we started this project the admin team felt that welcoming outsiders into our (wholesome, sane) Star Trek communities was the net-positive action. But as I said it became too much to handle so we unfortunately had to cut the cord.
