       How does data privacy work on the fediverse? What if I realise months later I want to remove certain posts, is it possible?I see from the ActivityPub spec that it is technically possible, but I’m guessing not all servers will follow this? Maybe someone runs an archival service?Are we left with the standard rule of the internet: Everything ever posted on the internet can never be fully removed? 🤔

       @exstral > How does data privacy work on the fediverse? What if I realise months later I want to remove certain posts, is it possible?You can delete a toot, which deletes it from your home server (#fosstodon, for you) and sends a request to delete it to all servers that have it.  Spec-compliant servers *should* honor that request, but…> Are we left with the standard rule of the internet: Everything ever posted on the internet can never be fully removed?Pretty much, yeah

       @codesections okay cool, and I understand it correctly that as soon as I toot something, that is posted to my homeserver, and then right away also distributes to all federated servers? Do those federated servers in turn spread it forward? Or are posts only sent 1 hop, as in federated servers always have a direct connection to each other?

So any server that gets your toot right away would be federated.1/2

       @exstral But, say you reply to Alice (on a different server) and Bob (on a third server) follows Alice but not you.  Then, if Bob clicked on Alice's toot and expanded it to see all replies, Bob's server would request the replies from Alice's server, and get your toot—even if Bob's server wasn't federated with #fosstodon.There are probably a few other cases like that (hashtag searches, maybe?  Not actually sure how that works)
