Edit: on second thought, since porn is a MAJOR traffic giant on the internet, they should be doing some kind of look into the sites they are listing for the most popular terms, but who knows what their motive is.. if these major illegal tubes are really doing something illegal then there should be a way for Google to get access to this information and ban their domain.. obviously no one is stopping the illegal tubes?
