Are you using torsocks to run bostr2?
I figured if the bouncer is not torified the outgoing websocket connections are leaking the public IP of the server to the connected relays. (The client is safe.)
My systemd service here in a #Raspiblitz PR: https://github.com/raspiblitz/raspiblitz/pull/4724/files#diff-0ffb074f869361719e03a7d89046a39b7890b10abe0895f60c0d8a50c3c3b520R136-R160
This amd the quoted post was broadcasted over Tor only from Amethyst to a bostr2 and a strfry instance.
