Longer Road to Permaban
IMO, there needs to be a lot more warnings and actions taken before the permanent suspension of the account. Permanently suspending someone's account should be the most severe form of punishment for the player of the game, with the mentality of the player not playing the game at all, not of one for them to recreate an account.
One 14 day suspension into a permaban is not enough warning, nor is there any warning that the next punishment will be a permanent suspension. Even Club Penguin had 4 different suspensions before the actual permanent suspension. A single two-week suspension is not enough if you want to see players change their behavior.
