Whenever there is betting there is a possibility of cheating. The key potential cheat on BetBacked (BB) is that a judge could try to wager on a bet she decides.
So, BB has the following rules:
To cheat, it remains possible for a judge to reach out to a bettor and propose that they split the profits from a favorable decision.
This cheat is fraud, though, with criminal penalties, which act as a deterrence.
Beyond these penalties, each BB bet has three judges. It’s highly unlikely that all three would independently reach out to the same bettor to collude.
