Has anyone ever used this ad network before? I set the ad cap (popunder) for max 2 for every 30 mins. Never checked it before, but today when I checked it, the popunder opened every few mins! (like I got 3 or 4 for 2 mins now). How come is this possible? Not to mention my impressions was insane, I got like 5k impression on exoclick but in here it's only 567. it would be awesome to hear your ad network recommendation or suggestions!
