Once you are banned from Google AdWords are you booted out forever or is there a dubious way in? Asks a victim of the ban at a forum .
According to Digital Point, some users have been banned from AdWords for bidding on certain keywords, on many occasions without prior notice. Suggestions include getting a new debit/credit card with a different billing address and using either a middle name as the first name. However, Google is good at finding banned users.
Another Digital Point user provides some advice, Ć¢ā‚¬Å“I don't think trying to circumvent the system is going to get you back into their "good books". If you're really desperate for some AdWords advertising, your only option might be to hire a large company that does various promotion like that (running ads for client's websites), as they'll presumably already have a premium AdWords account, and will be sure to follow the TOS anyway, so Google probably won't care. You'd basically be dealing entirely with the company, and they'd be handling all the AdWords activity. It would of course cost you quite a bit more than if you were able to have your own AdWords account, but you don't really have a lot of other options in that wayĆ¢ā‚¬Ā¯.
It is nearly impossible to get into AdWords after being banned as concluded in a chat transcript. On a humorous note, one user even suggests sending Google some flowers.
