I'm not talking about proxy or caching relays.
On NIP-65 you can specify "read" relays which should be used by others when replying or mentioning you and used by your client when reading your inbox.
That is where I'm saying one can select a relay that will reject stuff based on whatever criteria. https://pyramid.fiatjaf.com/inbox does that with a very dumb algorithm.
