yes, with something like twitter you can be sure public won't see it after you delete it, given that you were quick to delete it after posting (by mistake) and it wasn't that 'breaking news' for someone to screenshot it right away

it would be great to see effort and commitment of relays to respect deletion,

BUT

simplex blog about disappearing messages had a good point: with email you own email, when somebody sends it to you, it would be weird if they could remotely delete it from your computer. same with messages. if you are sovereign, how does someone else's ability to delete stuff from your machine play with it?

@simplex solved it by both parties having to decide if there is such thing as 'delete for anyone' in their chat, as somebody might've sold you some digital content and then they delete it?

so this will be an interesting thing
