Unfortunately, you have done something that looked suspicious under the rules set by a string of code that Zanzarino programmed way back when. You can expect that it will take a long time to get your account unbanned -- if it happens at all -- because Zanzarino is the only person who can unban it, and he's very very busy. So busy, in fact, that you cannot get in touch with him directly at all.
Your only hope is to PM
Scaredgirl, the board admin, and ask her to send Zanz an e-mail. Even she has rather poor luck in getting a response from him, but it's your best bet.
As much as it sucks and it's unfair and awful, you should probably, to be perfectly honest, commit to starting over from scratch. Even if Zanz does decide to look into your particular case, he probably won't do so for at least a month and he still might decide that you're lying and you hacked somehow based on what the logs show of your games.
I'm sorry to be the bearer of bad news, but it's probably best to get the full truth out there up front. Good luck!
