Ignore it. Defederate. Defederate with any instances that chose to federate with it. Keep the fediverse small and independent. It’s nice here, let’s keep it nice.

I keep asking but haven’t gotten an answer, why must instances that block meta also block those that federate with META? Wouldn’t blocking META be enough, as you wouldn’t see their posta, nor users, nor comments in any way after blovking the domain?

Is this punitive or is yhere a reason I’m mising?

I got the impression that somehow your activity 3rd hand can still be passed on via the intermediary instance to Threads, and then becomes part of their dataset. I could be wrong, I’m not sure how that information gets passed on in the backend.
