Stalking on Nostr is not a good idea, not just Jack but in general, because DMs are public and anyone can log in with an npub and see who's sending messages to whom. 

 Yes totally agree, people should go back to stalking their exes not strangers (just kidding).  

 Yes, stalking someone is bad, but the fact that everyone can see that you're stalking someone make it worst for the stalker I think. 

 For now we can log in with npubs and see the DMs without reading them.
