I joined the website and worked tirelessly for 3 days and i made 1500 $ then they asked me to complete a survey to check out my payment and the survey site doesn't work ! My hard work along with 1500 $ which is a big sum WENT DOWN THE DRAIN and there's more to it ... Today when i logged in after 7 days my earnings have become 200 $ ! THEY HAVE COMPLETELY CHEATED ME ! I would never recommend anyone using this website !

it looks like a really good site, and if you can get people to click the links you will make the money. But they ask you to 'take a survey' to prove that you are human and not a payout bot, but the survey site doesn't work, and since you can't take the survey you can't get your pay out. And the ONLY way of getting in touch with someone from support is an email address that doesn't work. So it's a lot of work for nothing.
