OK just spotted this, don't know how they do it.
Go to google.com type in adultporn as a search query (yes 1 word adultporn)
On the right side in the sponsored links bar I saw an ad for
Worldsex Free Porn
%100 Free Porn Videos
Animal Porn Horse Porn
www.worldsex.com
Strange
so I clicked the link and went to this site:
http://www.gelbana.net/free%5Fvideo/ all bestiallity crap
The weird thing is that
www.worldsex.com is in the advertisement as the site url. I also see it when searching for horse porn, you might want to look into this.
