well i am into warez.... n well we have a lot of popups.. we server 100k pops daily.... so u can imagine..

anyways we have tried all companies... and the results are like this...

clicksor pays the best for the popunders
cpxinteractive fills the full inventory...

so the final verdict... use clicksor for the main code and give cpx as the alternate code...

we have tried all... n paypopup had Trojans in them....
