I have been in the affiliate marketing for two years . And know know some guys get rich by play click fraud . Nowadays the domain parking company is just like the fat big .Everybody like to bite it . But when I see the ads on Facebook . I know it will be the end to Click fraud .Why ? Unlike the usual CPC advertisement , you have to login to see the ads . It is really a big problem for the Click fraud player . Just like why Google is shocked by Facebook . Google can not index Facebook’s pages if it don’t login . Really funny
