If your username is found to be incorrect or there has been input an email address instead of your Lost Ark Character Name then you will be disqualified.
Player IDs are stored when you enter a tournament, meaning that any changes made to a player's ID after they sign up for a tournament will not be updated on the roster. To avoid this change your username before signing up for a tournament or leave the tournament, change your game ID so that it is correct and then rejoin the tournament.
