As someone who has worked extensively in the GPT (get paid to) industry over the past 3 years, I can tell you that there are many legitimate paid survey sites (I am in fact posting one in the ad section after this post)
Vindale research, however, is not one of them. They have numerous complaints against them. To find real paying programs you can go to a site called GPT Boycott and see which ones are legit. There is a directory on there of seal of approval paying sites and a directory of boycotted sites.
I hope this helps
