I had been a member of opinion outpost and ipoll for years without problems. Recently, they kicked me out of both accounts saying "I had not been attentive" in my survey answers. As I have not changed the way I answer surveys over the years, I find this a hollow reason - especially when I had been a member of both for so long. I believe they just decided they needed trim the number of panelists - DO NOT JOIN either of these as they will kick you out for NO good reason and without warning. Do stay away!
