TIL what 0xchat is...very interesting. :)
Such as accepting people's join requests in nostr:nprofile1qqs9ajjs5p904ml92evlkayppdpx2n3zdrq6ejnw2wqphxrzmd62swspzemhxue69uhhyetvv9ujuvrcvd5xzapwvdhk6qgdwaehxw309aukzcn49ekk2qghwaehxw309aex2mrp0yh8x6tpd4ehgu3wvdhk6ynf30t, but still seeing their join requests 😬 And if I accept them again, they don't go away either. 
Discussion
I use it for most of my Nostr DMs and Nostr chats.
Ahhhh, that might be why I see a lot of profiles say something to the tune of "Don't DM me here."
Still learning the culture here. 📝
Some people say that because the old style of DMs leaked metadata. The new styles do not. We just need more clients to accept the newer implementations.
With all the encryption and ownerships that is out there, it'd be cool if somehow someone cracks the code on including notifications for screenshots at the protocol level.
