Nope it doesn't. We decided that it was hard enough getting advertising without having "adult" search. We focus on text analysis so we aren't very good at porn searches.
I need to look why you didn't get a message saying we don't do those kinds of searches.
Disabling ads is actually pretty hard. We had Adsense running until we got kicked for having results on "Jail Bait" those two words alone are not dirty. But I didn't focus on building long lists of dirty topics so we were returning results on that.
