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.

Mind if I ask what the instance that you’re planning to move to is? That sounds like a great defed list and I’d like to support that sort of behavior.
They're a regional instance. That should narrow it down a bit but I'm sorry I don't feel comfortable saying outright. They've been having server issues, I'd prefer to try to keep them from having moderation issues too, there's been a couple of people from shit just works brigading other instances. Most Lemmy instances have defederated from exploding heads at least.
if there are other instances that have defederated instances u want defederated, i recommend joining them, as you yourself seem to be aware of.
