Highly profitable campaign with forbidden method – popunders

Hey guys,

I’m running a very high profit campaign using popups and popunders, but the thing is my affiliate manager just told me that popunders are forbidden. I’m currently hiding the referrer, so they can’t see what’s the traffic source.

Is there any way he can found out I was running popunders and delete the conversions? Is there any efective way to distinguish between popups and popunders? Popups are allowed, popunders aren’t, but popunders are far more profitable.

Thanks!!
