I saw talk of them being federated with instances like "exploding heads" (literal neo-nazis) and "posting lolis rocks", along with having interactions from users there. Is that true? idk how to check for that, I can only just barely stumble around the normal forum interface.

If so, why? They've been going hard on purging communists user-by-user and comment-by-comment, which seems like a little bit of a secondary concern to nazis and pedos, especially something as simple as just blocking the instances at the very least. What's going on over there?

What I mentioned, if it is correct, might not be exhaustive, I'm just repeating what I heard about.
