Upvoting for the idea, it's pretty unique to this market and has some potential. Not going to lie though, if I saw a 15 different game threads hit /new that said "vote here and split the money," I would think it would be a little spammy and probably not read.

If this were to work, I would think it would work more in the context of "play of the day," where commenters on the thread post their favorite play and people vote on which one they like the most. It would keep it to one message per day and would reward the top upvoted winning commenters for sharing their wisdom with the crowd. People start building reputations as they start making better picks. People would lose reputation of they attempted to edit their comments(easy to tell on the blockchain).
