📊 Fediverse Awareness Check:

When you hit send on a post, your app sends copies of that post to be stored on up to over 40,000 connected servers (hard drives) around the world.

When you delete a post, it sends a request to those servers to delete their copy, but it can't always be guaranteed and your post may remain visible online.

Why "Delete" is complicated in the #Fediverse

Unlike X or Facebook where one company owns the only copy of your post, Mastodon and other Social Web apps use the #ActivityPub protocol.

When you post, your server (e.g. toot.wales) sends a copy to some number of servers (e.g. mastodon.social) - anywhere from one to 40,000 depending on a bunch of stuff.

When you delete, your server sends a Delete request to all those same servers.

Hi @jaz,
once published, it's public. Period.

I am very much for a "best before end" expiry hint on /everything/. Hoarders may keep it anyway. It's on their pile of compost then.
