I have seen many top websites like news,business,Food,travel sites are getting traffic from crowdflower. I have personally done the crowdflower task, So i have able to understand that many news websites are using crowdflower and also the news website i have seen that they are promoting the posts which are posted before 2005 but they have google adsense on their site and other adnetworks. Does google adsense won't see this as they hate paid traffic but they leave free to top websites? or it is the best option to get traffic?
