first time that i'm completely with you. it's a crime and it should be prosecuted by all imaginable means.
this cancer not only sucks off advertiser spendings but also throws an unfavorable light on the majority of hard-working honest content network publishers and reduces their earnings as well (whereas fraud apparently is also committed by rivalling advertisers on search and content).
however, as fraud rate stays manageable and roi is fine, most of us can live with it very well. no need to panic or cry for ppa.
