I might refine your blocking a bit further, by reviewing that "AdSenseSpam" sites relationship to your sold products. If they are making you money, then why block them? If not, then, by all means, a good move. I think we should all do that. The end result is that our ad costs will go down without hurting our sales.

We track where every sale came from and back link to that page to see what key words were used and what the results were from those pages. I have found no sales from many of these sites and multiple clicks within a short period of time from them. That is why I have choosen to block my ads from thier sites.

Also every time I see an adwords ad that says directory I like to click on it. Yes I admit that I cause fraudlent clicks! I just know it costs them money and my google stock to go up!
