At the moment, all non-official broker airlines are only suppose to have 1 plane, so its easy to tell if they are cheating, but what about later on in the game when people own thousands of aircrafts? I dun believe the team has enough man-power to search through each and every one of the accounts. Plus.. we don't want the admins to be over stressed do we? so thats why I'm suggesting the game to be closed until the problems is solved.
