I believe the videos could be shared like "non-winner" as well, it will be fine, nobody will be expecting payment for something that didn't win right? Well, that is not gonna happen. If you pick 5 videos and publish them on your youtube channel then the creators of those videos will want something in return, just "exposure" or what not is not enough and they will want payment.

Not because youtube videos will get payment because I am pretty sure couple thousand views will not be that much payment but because they helped with marketing so these videos are not just youtube videos but also videos that help windice get gamblers to their websites and since its impossible to calculate how much one video helped windice win how much from gamblers its going to be a tough sale on both sides.
