Out of curiosity is there any real evidence that there is a negative consequence for an advertiser marketing its brand on a porn/adult website? I'm a fairly well adjusted human being that also consumes pornography at times and i'm not sure I would personally be bothered with seeing an add for a luxury car brand or clothing designer (not-withstanding my general dislike of seeing any ad). I don't think it would influence my viewpoint of that brand one way or another (vs seeing it on any other site); but maybe subconsciously it would? Is there any actual research?
