It all depends on why you were banned.  You need to look closely at the ToS and the Rules.

If you were verified, a ban can be a number of issues.  Most of the time Chaturbate will give you a warning and if you do not take any notice of the warning for what ever reason and continue to break the rule, they will ban the account.

Be sure to email support at the right time of the day 18:00 GMT / 10:00 PDT onwards during the week is the best time to get in contact with them.  Just be sure to include your username and state when you were banned.
