Look at it this way, me, and I guess everyone else, just closes any pop under, or pop up window. Did a window that popped up and was closed immediately count as a "view"? The answer to that is yes and therefor it's not worth it, it doesn't bring any "real" traffic that actually reads what's on your pages, all it does for your money is give you a bad rep for being one of those annoying pop under people.
