Just got some more information from our ad company. They're not running the Weatherbug (or the FemaleAdvantage) campaign at all. They think it could be coming from some type of adware program that users may have inadvertantly installed on their computers, such as Gator, Gain, etc.

Also, a correction on my part; I assumed that our ad company cookie limited the popunders to one ad per campaign per day. That's not the case... actually the cookie limits the popunders to one per day, period. They've also told me that they haven't served _any_ pops to FlyerTalk today (4/2) or yesterday (4/1).

If you're getting multiple pops, and you have cookies set to accept, more than likely you have some other software running on your system (even in the background) that's serving ads.
