If you have been banned from Zynga Poker, there are a few things you can do to try and get your account reactivated. First, you will need to contact Zynga support and explain your situation. They may be able to review your account and determine if there was any wrongdoing on your part. If there was no wrongdoing, then Zynga may be able to reactivate your account for you.
However, this is not always the case and you may need to take additional steps on your own. One thing to keep in mind is that if you are banned from Zynga Poker for a long period of time, it may be difficult to get your account reactivated.
