I have been viewing friendster.com and i have came across some profiles with some very adult / pornographic image gallery's... and next to the images are google ads..... how do they get away with this ???
I think that is basically because google thinks the domain by itself is not an adult content domain. Granted some of the members have put up adult images in order to get more hits and traffic, but that by itself is not reason enough for google to ban the domain.
