Of the 5 reviews I* read, 2 of the entries had Malware/Trojan infections attributed to this site.... so How can my* WOT results page show "Excellent"..(?) when 40% of the submissions to WOT About* g.doubleclick.net reported Bad outcomes?? This isn't "just spam" the people are talking about, so, I ask Again... Why does MY* query about "g.doubleclick.net" result in an 'EXCELLENT' site review when clearly 40% of the WOT site submissions were NOT "excellent"..?? ..... And Why*, when I've Rated it 'yellow' / Be Cautious, does it Continue to say that my Rating is "Excellent"????
