I've been a part of this site for about a month - maybe longer - and have earned close to $20. You have to get at least $30 to request a payment.
I don't qualify for most surveys, so I do most of the offers. (They don't seem to get new offers so I'm stuck with having done the ones I've already done)
Also, most offers require you to spend money to make a portion of it back.
And, half of the sign ups I do, I don't get credited. I do use real & accurate info to sign up for offers.
I guess this is more for entertainment. I'm a stay at home mom, and I get bored when the baby sleeps so I use this site to preoccupy myself.
