I'm not worried about screenshots, most people understand not to do that. Rebroadcasting because they didn't realise it was a private relay that I had given them access to is more of a worry. If that can be stopped that's great. We probably need a way for people to buy virtual relays. I don't want to share pictures of my family publically, but if I could get them onto nostr I would like to in a way only they can see.
