@BarryCarlyon Well, I’ve now made a series of experiments. I made my bot join my own channel, banned it, and then attempted to send another message to my channel. There is no special USERNOTICE or any kind of response from the server, and I capture all incoming lines and display them while debugging… The bot joins, sends the message, the message is not displayed, and then nothing happens. No response such as “You are permanently banned from talking in…” or anything like it is sent back from the server. This really puzzles me. Is this USERNOTICE not part of IRC? Are you talking about some special “API signal” or something? I must be confused somehow about this.
