First, there is no central authority within #Nostr that could shadow ban or ban you. However, in theory, relay operators could ban you from their relay or clients could filter your npub. For the first case, be on as many relays as possible (not the spammy ones). That way, if one relay bans you, your posts still appear on the other relays. That's the good thing with Nostr.
