It's not scam for upgraded members. But it's scam for free members cos it never tells us that we have to upgrade to earn $ from them.
We have wasted our time a lot there for nothing!! I was just found this thread but I already clicked there till my eyes hurt for 3$ but got nothing finally cos I'm a free member there!!! They should tell from the very first in registration page that we have to pay $ to them to earn $ from them. It's a very wicked and low standard style. I do not appreciate it and recommend people not to go to that site.
