Hmmm... so what I have learned is that nostr clients will not let you scream into a void (they are getting too good at gossip).

Does anyone on here run a /dev/null relay that I can set as may sole relay to see if I can send a few notes into the void by broadcasting to that?

A nostr user should assume that every note they publish will be rebroadcast on relays far and wide with no discretion.
