Yup. It actually is enforced by the way. GM\'s do find you. My old name was Yeti, I liked it, but GM\'s didn\'t. It\'s a cryptid so it wasn\'t allowed.
Also, while you petition, you can PM the player with the name. A lot of the time they\'re new comers who don\'t know about the rule and what\'s allowed etc.. Let them know it should be either deleted and create a new one, or to contact a GM to change it.
