Should probably put this above, just so you know, people wouldn't need to read your needlessly long post about an "accusation" that has, well, nothing except your word for it.

In addition, I don't think fake accounts can do anything to players? The most damage it could do would be manipulation of the leaderboards of say highest wins/highest betters etc. since they can change that at will. Personal experience with games like dice, crash, etc. I don't think a game exists where the odds are affected by the number of players that bet, at least I haven't tried one (or I'm just that dumb to not remember about it).
