JS_Harris, Google only "catches" about 2% of the fraud from my estimates, others say they catch maybe 5% at best. Also from what I've read Google is the best at catching it so assume Yahoo and other networks have even higher fraud rates. 0% is acceptable - a third party company should audit and suggest refunds to the major search engines. While the recently increased transparency is great (especially on the Google content network), too much fraud still gets in.
