I had a really bad experience with this company recently. The guy named "Or Shalev" was after me to get a publisher account and promised me good rates for the ads that will be shown on my website. I also tried it out and stopped using it when i made around $20. I wanted to be sure that they pay money before i make those thousands of dollars by using the ads full time. I had a bitter experience of 2 months of discussions... and $20 was not paid and in the end... Mr. Or Shalev told me that i should F my self. Which is kinda rude way to talk.
Beware of their false promises they will try to lure u in with big promises but they don't pay money. I would not recommend you use this company there are many good companies out there that pay on time.
