Is zpag.es Safe?

I wonder why this site is still online?? I tried to sign up and do links for them, they claim to "pay" more than sites like ADF.LY So in fact, they don't pay at all, I speak from my own exp. I managed to have some earning on the board but one day I logged in and got this surprise: "System Maintenance: ***** had been suffered from system error on 8 Nov 2011. Part of the impression and revenue data on 6-7 Nov were incorrect, and some of the users might be affected. After an emergency repair on our system last night, all the data is generated back to normal now. Please kindly accept our heartfelt apology for any inconvenience caused." -Suddenly ALL my earnings became 0$ and they try to give a pathetic excuse for this as you saw above. I tried to contact but they didn't even reply. This site should be taken down - nuff said, don't let yourselves get fooled by them.

Promotes one or more fraudulent "easy money" schemes which typically cannibalize the resources of their own new members as well as legitimate businesses through obscure, distributed networks of like-minded affiliates, straw men, and human or robotic zombie operators. Commonly, these schemes periodically reorganize under an alleged "crisis" after exhausting downstream members' resources. Because the pervasity of these schemes generally degrades the Internet's quality of information and resources, everyone loses. This site provides a link-shortening service for sites which promote "Paid-To-Click" click fraud schemes which employ distributed zombie click spamming to artificially inflate affiliates' page rank and/or to drain competitors' pay-per-click advertising funds, a subject of successful lawsuits. Usually these web sites pose no immediate technical threat to visitors' computers. Details: *****
