Help me prove that those are indeed scam sites

I have been thinking of doing this as of test purpose, to prove the words of some people that thease sites are indeed scams (some say legit).

First would be AW Surveys, where you get 25$ (I think it was) with the starter surveys and after that you get only one survey per month with 1$ value, but you can also get 1,25$ for every referral. So I would be glad if some of you will just join under my ref link, to see if they pay me or cancel my membership before reaching the payout of 75$. I currently have 30,25$ there, so I would need 36 people to join.

EDIT: Yes I know that most of the people say that the site is a scam, but since there is some that say they have been paid by them I just want to see it myself. So if anyone has some spare minutes to just join it I will appriciate it :)


Next is PayingPTR.com where you get a whopping 1$ per mail you read in their inbox (probably a scam, but I already have 300$ in my account and 500$ is the minimum payout, so I would sure like to prove the scam of this site). You can view over 10 emails per day and also some PTC links that give you 50c. Will see about the scamness of this site in some weeks and would be great if someone will help me on the way! :)

EDIT: No need to join. I already have 350$ on my account there and will take a bit over a week probably till I can if ever make a payout request.

Finally we have Cloverbux.info where you get 6 ads per day and each is worth 7 cents. The cashout minimum is 40$ and I currently have 7,56$ there, so some refs would speed up the process there.

EDIT: It seems that the site is not working properly, since it does not show if you have any referrals and I should have atleast one I think, so no point in joining - I just need to get to the payout on my own.
