There is now way to unban your account. Well no good way. Your account can be unbanned for about 5 minutes or so but after that you will get a permanent bann.
I think there's a reason for your ban and you should not create a new account to ask for unban because you'll may get permanent or iP-ban! The best way to get your account back is waiting for unban so you can use it again

Its only 1 month, every thing will be there when that month is up. Just be glad it isn't a lifetime. I have gotten a lifetime ban and I have had to start all over. So just log in when that month is up.
I think it depends of how much you duplicate cannons. I've got an account who has been banned because i duplicate too much voodoo cannons...
While i stay under 400 for each of them it's fine i've got no problem =)
