I mentioned this yesterday in the other thread; google does a heck of a good job scrubbing porn results (let alone kp) from their own search results for the term 'sex' on the first page results anyway
http://www.google.com/search?q=sex . with any luck they'll take the head's up and flag a few terms as worthy of being checked out by a human before posting if they appear in their adwords submissions. 'Preteen lolitas' would seem like a good red alert flag to me
