Yes, that's very well possible and something that did not occur to me. I've owned a run a forum site for some years now and if I ban a member it still gives their username, but below that it says 'Banned'.Its posts they made while they were still members. Once banned or unregistered all previous posts turn to what you are seeing.
Have no idea who he is, but I can assure you that the members I've banned have never been missed by any of my member's. :wink:The person in question was a very knowledgable piper that made a mistake. He is no longer with us and is truly missed.
