Thank you for pointing out the terms section, and the fact that you can see more microscopically the terms that are actually clicked upon.
Did you ever also check to see what actually is showing up when a customer clicks on one of the ads on your pages? For example, for the $10 ppc ad, one would certainly be curious as to what exactly is being viewed and done at that point.
Admittedly, I've never tried, out of respect for the integrity of the ad-company services and not seeing a "zero click" or non-counted click option readily available. Obviously one does not want to violate the TOS, and cause a click that inadvertently appears to be an attempt to create undue revenue.
