Count me in as one of the bad guys - I only use 2 email addys though, mine and hubby uses his. Our demos are the same except for age and sex. I really thought this was okay. I know we have gotten the same survey before - maybe 2-3 days apart but obviously my answers are going to be different than his so we aren't duplicating the surveys. I haven't used any other sites in about 6 months (except pinecone), In fact, one time greenfield routed me to a pinecone survey which I thought was weird and I exited out of it before I even found out what it was for because I didn't want there to be any conflicts.
Tricia, I hope you get this fixed so that you can feel better about it - just remember you have a whole lot of people here behind you.
