I don't think you can prevent an event from being published to it, other than enforcing some kind of whitelist, whether it's pubkey, tag, whatever based.
that's what I mean by clients needing to interact with relays better and de-commoditize them.
We'll get there
when you say “publish to it” what is the it?
I’m suggesting a client respect a relay running a no rebroadcast nip, so if it pulls from that relay, and then I interact with it, it won’t rebroadcast the note I’m replying too if it came from the topic specific relay. I’m not suggesting relays stop it from being published too.
