AOL has a page they point you to, listing reasons you might be suspended. The only one that I could see applying says "If we don't know your age, we'll suspend you, since we don't allow anyone under 13 to have an account; click here to register with a credit card". But when I click there, it says to log in, and won't let me log in, because duh, my account has been suspended!
I suppose I could just create a new AIM account with a new name. Any better ideas?
