t's nothing like 15 minutes, but Lemmy doesn't federate posts instantly either.

And for Hubzilla, it depends on the outgoing queue. It can range from instant to awhile.

But we can edit and delete our posts, and most major fediverse platforms will comply with our update and delete requests. But as users who understand a bit about decentralized social media, we understand that once it is sent, there is no guarantee that third parties will delete or update it. The average Threads user probably does not understand that yet.

Apparently they either don't realize that there is a Update mechanism in ActivityPub that allows you to edit your post any time, or this is a temporary measure until they implement it.
