I am a member of this sites since of Oktober, and they are really paying. The method of making money is simple, you only have to get referrals and only 4 of them. There is 10 level of downline. You get paid 0,001$ for each days login, and 0,0001$ for refs login each day. Only one login per day you get paid. So if you make your calculations you can make 3145.76$ monthly.
There are other benefits: cheap ads and banners.
So far I got 2 payments. Here I post one of them. It is not much but finally i have found a site that is paying, and that feels GOOD :D :D :D
