devnull, 
So someone deleted their Mastodon account and now my instance is receiving an Undo(Announce) for everything they've ever done.
This ... is ... concerning, considering one should assume a single Delete(Actor) should automatically handle all of the side effects?
I'm not particularly worried about the noise, bandwidth, or cycles, it's mostly just out of principle that I think this is weird.
I think @hrefna tooted about this awhile back too.
