Who owns Quickthoughts? You need to know.

Quickthoughts is run by Survey Sampling International, LLC , which is a division of Research Now. Research Now also runs survey sites like E-Rewards and Valued Opinions. I've noticed that they won't let you be a member of more than one of their sites. You'll get shut down/blocked after a short time if your email matches another one of their survey boards. I suspect that explains why some people are having problems cashing out and running surveys.
