Google has gotten way too big, in terms of projects, to have time to totally police the Internet. Further, the Internet has gotten way to big for Google, so things will fall through the cracks. I would advise not to try and “trick” Google, as it may only come back to haunt you. How do you know that if they find you and ban your site, that they won’t seek out your other sites, and ban them as well ? Is it worth a few week (or months) of illegal Adwords ?
