If a relay can can shadow the content of nostr users, how do you shadow a relay from receiving your content? You can't right? #asknostr

What does it mean “to shadow”?
shadow ban people from displaying on their app / site or in their "trending" section.
The Nostr protocol is optimized for circumventing censorship. If a relay censors content, users can switch to other relays. For this reason people generally use multiple relays simultaneously.
Stopping a particular party from receiving content is antithetical to Nostr’s design and ethos. So, to answer your original question, no, I don’t think there’s a practical way to prevent specific relays from receiving one’s notes.
Good point, come to think of it... you don't own your notes but the #nostr network does.
