Google Seeking Ad Fraud

In Adage.  A visit to a Google site that is devoted to identifying Ad Fraud.   All this has evolved quite a bit.  Been attacked a few times myself.   Now the attackers are very sophisticated.  Ad fraud has received relatively little attention, because it is less dramatic than deeper financial frauds.  But now  patterns are being sought, and found.  Hopefully these same skills will  be reapplied to make the Net a safer place.
