Anybody get a restaurant online study from 20/20?

[NFriday]

Hi- 20/20 has emailed me at least three times about an online restaurant panel they are doing.  I did not try to get in because I don't go out to eat that much, and so I assumed I would not be eligible, and the study I think they said would take me an hour to complete, and all they were compensating me with was a $50 GC to use at a restaurant.  I suspect it is one of those restaurant.com cards or something similar.  It is hard to find restaurants that take those.  Did anybody here sign up for the study?  They must be desperate for people if they have emailed me that often.
