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.

I was also kinda surprised that sh.itjust.works doesn't block exploding-heads as most instances I'm aware of do. That coupled with the fact that the instance doesn't block them but blocks lemmygrad made me think at first sh.itjust.works was going to be some far-right instance, but from what I've seen it isn't. Though, I don't understand why sh.itjust.works would want to federate with them, considering their content often violates the rules of the instance.
To be fair, I'm a pretty radical leftist and Lemmygrad is a giant cesspool for me.
