I don't think this is a universally held standard, esp. that Mastodon's block semantics make that very hard to do after the fact (because the blocked instances might not see the "user moved" message, so followers won't notice; also follows from blocked instances get dropped on the floor immediately last I've checked). I think at least some people would be way less prescriptive if that was commonly understood as a baseline standard.
