I have also been paid and I am a regular member here. My payment was really quick but I never doubted for a moment that this site was legitimate, We have an active admin here (you can ask questions on the Answeree thread) which is always a good sign, and if they are not about, often other more experienced members will try to help you.
We have had a few changes made here since I joined in July and although I had my reservations at first I can see that they were for the benefit of the site and I think the quality of the answers and comments are improving. I have seen a payment proof posted on The Beer Money Forum so you could check that out too. It takes a while to reach cashout and your answers will need to be checked, but this site is definitely not a scam.
