Anyone can vote in polls. I could make 40 new accounts right now and vote anything on the poll.
On to the main point, maybe this is not a ponzi. Maybe this is a legitimate game that will outlive both JD and PD.
But, it is still an investor based game.
Can you disagree with that? Can you claim that whether a player wins or loses is independant of other users joining?
By being placed in the Investor-based games subforum, you aren't being called a scam.
Unfortunately though, your game is rather similar to ponzis. It isn't going to get out of the Investor-based games subforum and it wouldn't make sense if it did.
Stay legit, and people might still use it anyways.
According to your logic, any dice game, that accepts investment in the bankroll, should also be moved to Investor-based games subforum.
