Note from @calle on Oct 18, 2023, 10:18 AM:
Someone posted an image of my encrypted nostr DMs on Twitter. Of course I know that it's possible to see the metadata but I didn't realize how creepy it feels. You can see who I talk to and when. You could deduce my social circles, maybe even real world activity related to my messaging patterns.From now on, I will stop using normal DMs on nostr. The traces they leave is horrifying and you shouldn't use DMs either.Please do not send me any DMs from your npub if you have something to communicate to me.Use a random npub or a giftwrap or use a different method or use a different network to reach me.Nostr DMs have always been a complete privacy hell and I urge anyone to realize this and act accordingly.I repeat: DO NOT DM ME. I WONT DM YOU.
I think NIP-17 (old 24) Sealed Gift-Wrapped Messages for Private DMs and Small Group Chats is going to help against this but I haven't looked into the details yet. So if someone can share details, would be much appreciated :)
