They would never implement it because there is no valid signal here. The vast majority of users would just thumbs down every ad they see because they believe that will result in less ads.

This... just doesn't apply to the scheme described:

>> If I clicked the ad, thumbs up, if not thumbs down. With appropriate weights this can work.
