I have a site about escorts, so I was checking today yahoo for "submissive escorts london" and got a whole bunch of spammy sites offering to install obviously some kind of hidden software: http://search.yahoo.com/search?p=su...on&ei=UTF-8&fr=yfp-t-501&xargs=0&pstart=1&b=1 So I am wondering how that is possible that in 2008 Yahoo still stays a risky search engine...
