Good evening. I'm not sure. It was ages. I'm guessing it was Piwobrody
Not seeing anyone by that user name. Without that or the e-mail you used to register on the forums I can't really look into what the cause of your ban is.
I also recommend that you clear your cache and check again if you're still listed as banned. Under certain circumstances we limit site traffic and it gives people a notification of being banned. This is not a permanent ban.
