I was using this site for many years, most of the surveys worked, I got points and redeemed points for gift cards. Suddenly in the last few weeks they suspended my account permanently for multiple violations. I did not do any violations. They do not give you a reason, it's all a secret, and in their Terms & Conditions it says they can do what they want, when they want and don't have to tell you a thing.
That is such poor service and what's the secrecy about a person's own account and telling the person what they think they did. You will never know why they do what they do or if they had a reason to do what they do. Stay away from this site, you will be wasting a lot of your time and they'll pull that on you.

It seems Rewards Central has closed down. The site isn't working anymore, hasn't been working for a while, there's no more surveys, when you write to someone there's no response. Not sure why they've just decided to give up and leave everybody hanging, with no information and no notice. They should take down the website so people don't get sucked in.
