You got kind of "lucky" that the ad is running at all because their policy is to not allow sites that use terms like "boys" "twinks" "girls" etc. because they consider them to be "teen porn concepts." It may still get disapproved within a few days.

As for the keywords, I agree... They use a broken automated filter that blocks certain keywords for being "not adult enough" when running adult ads. And basically it's a retarded system. They rely heavily on this broken algorithm and it makes it all the more difficult to turn a profit anymore with adult ads because you can't target appropriately.

We need more search competition.
