I pay for my Gmail account, but there is still no way for me to disable this harvesting as far as I can tell. As for the ad tracking bit, there is an extension called AdNauseam that google has repeatedly banned on the chrome store, but it essentially does what you said - register a click on most ads while simultaneously blocking the ads from rendering.
