IDK either if they are attached to cookies, that would be something to know. To me, THAT would be a great marketing tool that I would "fall" for... knowing that if I take the survey the first time it comes up, I won't have to take it again???? However, would that just slot me for the next one in queue and not give me a few days/weeks of break from the popups? Like I said, I don't know, but it is interesting.
