> I believe there is a whole world of click-fraud with Google and Facebook in this which noone is tracking
I believe it's actually a little more subtle than that. Google and Facebook don't have to commit fraud, and arguably their business model is to be a kind of middleman for fraudsters. They can be doing everything ostensibly above-board (and I would argue are) but profiting from the combination of advertisers and click farms.
