I actually did win a trip to workout with an instructor, worth a few hundred dollars at least. I will include this information in my profile, although I do feel that I can be objective about said instructor's workouts, as I have posted both positive and negative comments about her workouts/customer service before. I will no longer comment on that instructor's workouts, though, because I feel that people may question my motives (I can certainly understand why they might).
I think the new disclosure policy is a very good idea.
