> So if you have any sort of business where people pay you per click

This. This is the problem -- pay-per-click is completely and utterly broken, and has been ever since people figured out how to use bots effectively. For one, PPC is simply not compatible with real-time reporting, but there are myriad other problems with it.

And honestly, I don't know if it's even really a problem worth trying to solve, since there are better models out there already. "CPA" ads [1] are by no means perfect, but they obviate almost all of the problems you mention simply by their definition: the advertiser does not pay unless whoever clicked on the ad does something "interesting". Usually, this can mean anything from signing up, to buying something, to simply generating a sales lead, but the important thing is that "interesting" is defined by the advertiser themselves. Not by, say, Facebook.

Full disclosure: I'm an engineer at a startup that does, among other things, CPA-based ad targeting.
