Could relays self-propogate note references, without content, so people can see that something was posted on the relay and which one they would need to subscribe to? The note content could just be "Note posted to wss:/something.nostr" which would bring awareness to users on missing notes. The more centralization gets abused the more users will see note references, with an implied suggestion to use said relays.

Shut me down lightly 🤣
