PieFed sends delete requests to every known server, including defederated ones. I’ve seen a ton of delete requests from Mastodon too, for accounts that don’t exist on PieFed so it looks like Mastodon does that too. No idea about other fedi platforms.















PieFed has this in the admin area:
So admins don’t need to stay on top of the latest defederation drama, just choose who to outsource that work to. From that baseline you can add more defederations manually.
