AFAIK, Guru3D has not much control over which ads are displayed. it geo-located as well, so they would have to validate for every possible combination of countries. They don't. It would be nice if Hilbert could explan the interaction, and tiering, available with these ad companies, if he's allowed to talk about it. I sometimes get extremely dubious ads from Guru3D (and others). Do you think "Free Software Converter" seems like a good ad ?
