Why it's a scam
If you're an upgraded member, you can cash out for $5000. Not sure what the minimum is for free members. But what does it matter? You won't see that money anyway...
How they make money
Different prices on package plans for advertisers.
Hoping that free members will pay $55-$65 to upgrade.
I'm not sure who would believe that only 2,300 members can earn almost a billion dollars.
