Banned because of nickname?

Hi. I've been using the nickname "rofl" for several years now, and I have been playing on your server as well while using this nickname. But today [IG]Abe decided that this was an improper nickname and banned me for using it. I am not sure if he is just having a bad day, since I know i have been playing lots of games with him online as well in the past, but today he decided that this nickname was "improper". It is only a temporary ban, but I really think you should reconsider when and why you ban people if you want people to keep playing on your server.
