Well throw me into the mess of this one. I know I've take surveys that were very similar when I've changed emails, though different questions were asked and a different actual product was shown.
I also have alot of people in my family in very different age and income brackets to rely on some as far away as Nevada, so I'm sure that just looks totally wonky to Greenfield. Though I've really only had 4 or 5 of them take surveys.
I just gave my January survey bonus to the Make a Wish Foundation in the rewards section. I don't need this hanging over my head and truly never meant any fraud out of it. So at least that money will go to something good.
I do hope they come up with some concrete rules so this can all be cleared up and SR doesn't get hurt.
