Maybe you are encountering the "fake" questions they stick into the surveys?

One thing I noticed is that the profile questions had fake questions inserted to prevent people from using a bot or just clicking anything to get through the screens. One question was something to the effect of

"in order to make sure you computer can display images, please click the picture of the chocolate chip cookie"

Very sneaky. The surveys are completely bogus and any company using their results for anything meaningful is just being silly. I will continue to milk these programs for free miles.
