Well the first thing you got banned for you did do.
As for the second account thing, I wasn't the one who banned you, so... I'll get hold of the mod who did and find out.
Btw: Don't create threads asking why you were banned. And if you feel you HAVE to create a thread to ask rather than use the Contact page, it should be in the Support section. But you really shouldn't make a thread about it, you should just use the contact link. Therefore I'll lock this thread.
