So I've been thinking about this.. what about edit? Can relays refuse an edit?
That may solve the delete thing.. 

 We don't really have edit. We have delete, but it's only as good as the relays that honor a delete. 

 just use pastebin if you want edit and delete 

 Pastebin, the modern social network.
