So you change your name to "C Plus" and now your asking us why did we ban you? You will be unbanned by a high staff when we are available. In normal circumstances we would approve a unban quickly but since you this ban was self inflicted you can wait. Hopefully in future you wont change your name to something stupid and if you do then dont moan when an admin bans you.
Post your steam ID here so i can unban you later.
