Yes, it's true. All they want you to do is to visit the website and everytime the progress bar reach 100%, you can request a payment.
With the new feature you can also promote the website and if the winner is comming from your link, you will receive 10% of what that person win. The visitor will be recorded for 30 days so if you send a person to that website and that person win something after 25 days, you will still receive the 10%.
I don't know how long time this website will last before adsense ban it but I really like the idea "Money For Nothing" :)
