Do you know what would be cool? A way of federating post deletion.
Like, it doesn't have to be a "hey we deleted this post" message, because that's got a lot of potential abuses, but even just a "hey, recheck the status of this post", and then if the post is gone, the instances it federated to could delete it from the db.
@InspectorCaracal that seems to already be happening (except when toots federate to gnu social) https://github.com/tootsuite/mastodon/issues/2458
@InspectorCaracal i don't know enough about these things to know if anything (else) could go wrong, though :)
