I tried the survey once through them and it was declined. I don't know why since I finished the survey and got the "congratulations" message at the end. The only thing I can think of is that they are tracking by IP, not email, and I think you can only do one survey per 24 hours. The time I was declined, I may have done a survey through creationsrewards within the 24 hours. It was a different email addy but if they are tracking ip's then I suppose that could be the problem.
