I was searching one of my domains in Yahoo and Google and found a page on this site http://www.leading-special-association.be/ that had 1 link unit and 3 adsense blocks, all stacked vertically, then at the bottom was all the keywords, page titles, and descriptions from one of my websites! This domain has 934 pages listed in Yahoo, and it looks like all of them are abusing the system. I did email Google.
Something tells me Google isn't going to listen and is going to just give them a slap on the wrist in the form of banning from the Google SERPs, whilst Yahoo was their prime target anyways.
