So, I tried. In several days I collected over 80k views and over 30 clicks with a simple banner. I never use any popup on my websites. Everybody hate them and I didn't want to waste my visitors.
So after five days of experiment with 80k views my balance is $0.000. Absolute zero. No one poor cent. I emailed my manager and asked about it. No answer after 5 days.
In this way I can make conclusions:

- Popisle don't care about customers, they don't replay your emails.
- Absolutely poor earnings, or not earnings at all, at least with simple banner. But I'm sure the same is with popups.
- I wasted my time and ad slots. With this kind of views I earn $20 with other network.

BTW, my visitors come from 'good' countries: USA, Canada, Europe, Australia and similar.
Don't waste your time and precious space on your websites.
