I know of a competitor that has multiple sites and when you click on one of his sites from google, it redirects you to another one of his sites that has lots of ads and offer.
Pretty clever if you ask me especially with panda. Use 1 website with only unique content and no ads and have it redirect to the one where you can actually make money. A pretty simple if referrer == google trick. One would think google would be on to this by now.
