I went ahead and filled in the rest of my info and clicked "join" and it basically gave me the same survey opportunities. I put an email in to them to ask why the change but I suspect it is just because they are continuing to augment the profile information. The terms still state that they cannot sell your information. And my contract with them says that they cannot use my members' information for themselves.

I just took a 10 minute survey for a $2 credit. That has been my favorite so far!
