I'm sorry to hear that you're banned, but, if you're banned, you're banned. There's always a reason for it.
Then again..... You're not meant to discuss or post any kind of ban/kick matter on the forum. If you need to discuss this with someone, you need to PM one of the mods/admins.
I think you'll have to simply wait out your ban, I mean.. Half a day isn't too much. ;3
Relax and draw/play another game/watch a show or go out with your friends, there are a lot of things to do. ^^
