That's why the crime could only be proven by tracing the money -- high-level players operate at so many actions per minute that Commander Data would need slow-motion replay. But tens of thousands of dollars transferred from known criminals to a team's players and coach is a tell even the n00biest Protoss could follow. It's much easier to trace mob money in meatspace than to tell when a pro player is throwing an eMatch because our world has carefully assembled only the shittiest bits of every cyberpunk story ever written.
Not all such cons even try to be clever. Dot Esports reports that Team iBUYPOWER took money to throw a major Counter-Strike match, then threw it more obviously than a drunken clown with a bucket of whitewash. They went at their enemies like a wave of puppies that had been trained to find treats in enemy gun barrels, laughing out loud while they lost by a frankly ludicrous 16-4. They couldn't have more comically fixed the result if they'd been the Harlem Globetrotters. Even stupider than the team was their managers, who had refused to pay the players and told them to make their own money from advertising. We guess they decided to make money by "advertising" that they were losing.
Who knew guys nicknamed "Anger," "Dazed," and "Skadoodle" wouldn't be criminal masterminds?
