(Noob question): How is it different? People can still "request to delete" their notes, is there a more permanent repository of old content or something?
lot of tweets going to be deleted over the next few days by prime trust promoters - nostr fixes this
Discussion
Requests could be acted upon by the client, if they are designed to do so and if they got the delete request relayed by the relay - which is never guaranteed, and depends on the user's relay setup.
Technically, each note (post OR delete) is a seperate event traveling independently through the connected relays.
