a.w. surveys.

this one is famous!
but it hasn't a good reputation and it's not for less
when you join them, you'll find surveys to make 27 dollars.
so, that's it, you'll never get a new survey to take and you'll never reach the minimum payout (75 dollars)
the only way to reach the minimum payout is reffering friends to earn extremely high 1,25 dollars. if you do it, they'll flag your account for fraudulent activities and you'll simply won't get your payment!
there's a really good website about this. you can check it here
