(at least this should be the way).

if you are promoting a porn tube on a popunder and you have 20 K visitors per day with a good holding time and number of pages viewed it already proves my statement because you seems to be smart collecting traffic but not smart in advertising strategies.

did you ever thing where this pops are shown and WHEN ?

popunders are opening mostly on similar sites and the user who see your pop was in most cases already "successful".
this is like trying to open a hot dog stand at the EXIT of a restaurant.
think about that and you will know why that will not work.
if you want to catch horny users you should try to catch them WHILE they are horny and not after.
