I assume these people are using some program that handles registration and commencing over and over? Since otherwise they'd have to hit the buttons to commence every few min in which case they might as well do the race right? Allowing people to bot for rewards like that isn't fair to PS4 players since we don't have a way to continually register and accept commencing a race without being at our console... so while they can just rank their Chocobo up overnight while they're sleeping, those of us who can't are placed at an unfair advantage (as compared to a fair advantage another player who levels up legitimately would gain).
