You still need someone to organize the tournament and generate pairings. You need someone who knows the rules about how to handle game glitches and know how to recognize if someone is triggering a glitch intentionally. The judge also needs to monitor player behavior outside of the game (When does a player celebration cross into taunting? When does a player reaction count as violent or threatening?)
