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.
What is a casual user supposed to think when a new search engine claims that there are no results whatsoever for "Sex" on the Internet, period?
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.
