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.

To put another spin on it, lemmygrad and exploding heads have an old beef with each other that predates the reddit migration. Far-left vs far-right, it's not rocket science. As an example try typing in lemmygrad.com and see which instance it takes you to.
Now ask yourself what it tells people when sh.itjust.works has lemmygrad defederated but not EH. It's an endorsement, no?
Exploding Heads has never defederated lemmygrad. We invite diverse opinions, discussion, and debate.
