The last few posts made here, they’ve shown up, made the most inane, idiotic, and pointless comments, upvoted each other in a frenzy of circle jerking, and generally made a pest of themselves.
They’re a nuisance, and add nothing of value to the Lemmy experience.
As an afterthought, perhaps if they want to stop being defederated by instances they should have a good long think about how they interact with other communities. Shitposting can be fun but it’s stupid and rude when you’re entering someone else’s space.
