I don't know exactly why, but I know you will not get answers from the mods here regarding a ban. You have to go through support. Furthermore, spamming the forums and posting the same thread over and over will get you in trouble on here too.
The forums are not the place to discuss actions taken on an individual account. This thread will now be closed, but you can read more info about bans by following the link below.
