There are other methods outside of a in-game lock that might prove effective. If the player in question is of such detriment to the realm or heck the Islands game play in general. Then he should be exiled from the island indefinitely. A additional course of action would be the route of fining him travel expenses for his characters relocation to another island. Reset their honor and Prestige, heck even going as far as taking fame points away from the player themselves. Taking away someones long worked for achievements stings harder then a permanent ban.
