Why doesn't a company like Google or even a site like Facebook/Youtube use content blockers on a day like April Fool's Day? It would earn an insane amt of money based on their avg users per day if they partnered up with CPA LEad. Take for example Facebook. It generates around 1.5 billion dollars per quarter. However, there are 1 billion active users per day. Even if just a very modest 10% completed a survey ad to enter the site on that day, it would generate very nice revenue.. so why don't these companies do that?
