It's not just mintvine, they all do it, not to mention the ones that make you pay to get your reward. We should all complain to the survey panels about the rewards but I don't think it will do any good. I am hoping that the companies that hire them will hold them accountable. I wrote another one the other day, from now on if the survey gives contact info for the company conducting the survey I will write and tell them how little we are getting paid.
