I agree completely with the previous report I read regarding MindField. They require information for a particular survey and after I have filled in all they ask for, I am told I do not qualify. Too, I have tried to unsubscribe and have been given links to do so, but when that screens appears, there is nowhere to complete the unsubscribe request. I have even tried blocking them and it seems not to work. They must be using different email addresses each time. Why? Perhaps the previous report was correct in that they are using my information to sell for spam. Or perhaps they are selling my information as if I qualified and just not paying me for it.
