A new web site quietly appeared earlier this year and a little bird tells us that it’s being run by a group of ad networks seeking to exchange information on impressions fraud. StopAdFraud.org currently only has three posts up but each has details on specific web sites that have allegedly caused fraudulent activity to occur.

In one case they refer to the work of the anti-fraud researcher Ben Edelman to describe a case in which companies apparently bought traffic to push into their own nested iframe ads, “which in turn would contain advertising tags from dozens of different advertising networks.” This arrangement thus gave them hundreds of ad calls from one purchased impression.

Clearly StopAdFraud.org is operating at a low level of activity right now, but if ad networks can collaborate to fight scams of the sort described, it must be good for all of us in the performance advertising industry.
