I just read the announcements and it seems to me the punishment for misusing MPs is already set.
Quote from Mur: "As you know, wishpoints given on questionable reasons or on no reason at all, can be canceled by me if the situation is serious enough (meaning a short reason lacking details might be enough depending if quest was publicly known and there are no suspicions regarding the winners, but in other cases might lead to canceling of that WP if not enough proof exists regarding the legitimacy of the reward, quest, or reason. An other use of these logs would be to ban players that missuse their WP codes by giving them based on weak reasons, from receiving any other WP from their Kings."
If these actions in the list are seen as unjust then he can take action, and revoke said points and ban the players from getting anymore codes.
