Interesting, blocking and click fraud all in one package :-) As many sites live and die by their "traffic quality score" this seems like it would negatively impact that in a serious way. It seems to me that could get a site in trouble with its ad network, and if it were Google there have been examples where it just gets all of its ad revenue revoked/tossed without resource.

So it seems like this might kill smaller indie sites if it became popular. Is that the goal?
