I have a couple of sites I want to sell, and one of them can only run YPN. Google will not allow their ads on it because it deals with guns (BB guns, not firearms). I know that sounds crazy, but they get to make the rules. I'm wondering if any of you has ever sold a site that just has YPN on it, and if so, was it more difficult (if you have any comparison experiences) than selling a site that can run AdSense ads as well? Thanks!
