I noticed that JakeCruise, Titancash droped their ratios 2-3 times for last month, I checked their sites and found, that they start using popups. Titancash rep said that they pass coockies and stuff and everething is fine, BUT what about ratio drop and 0 sales and clicks on programs they use on popup? (btw, you get this popup onload when click join page)
Same with Jakepays.

I think everethin is fine ON THEIR side, but what about affiliates? Use popups for your own traffic, let affiliates choose what they want for their surfers.
