Create a new npub
Discussion
This method can, can let the client to do this thing, want to private chat, randomly create a new account, chat after the abandonment.
Multi user clients might make this feasible
Is there a client implementation already? I haven't used it
It would also be helpful to have an option to optionally attach some signature from the parent account to prove your identity to the person you try to DM.
Otherwise, it would be lot of new npubs saying "Hi, I'm Michael Saylor, and here's a free Bitcoin"
