I am here to report popmyads.com.
I delivered their popunders on my site for nearly a week's time. My site has got several hundreds of pageviews everyday. However, their statistics (which is not realtime) show only 0-3 popunders everyday! The earnings are decreased day by day even though they showed 1-2 impressions everyday!
When I asked about that, the CEO just said our site didn't meet their requirement! There's no minimum requirement mentioned on the site in fact!
Lastly, no payment of course. Definitely a scam!
