How do these betting sites handle real-time events? I believe there was a case recently where a man at the Australian Open tennis in Melbourne was arrested for transmitting point information outside the stadium before it could be broadcast on television (there is always broadcast delay), which obviously could give you a big advantage. I think European football ones go into a vol auction (pause betting) when a goal is scored? But you could have a guy sitting in the stadium, wired up with a buzzer to press when a striker goes one on one with a goalie, or a penalty is awarded, and then just go all-in on the market? The whole thing is a can of worms.
