I've had this happen to me multiple times, and even by a staff member. If this is a rule, it needs to start being enforced more.
you actually can just kidnap someone and leave them there, just run away, you dont have to do anything with them. herb is wrong about that rule... the rule was removed from motd a very long time ago.. As for kidnapping, people really dont even kidnap anymore, there is only a few people that spam beast potions and kidnap and they dont even play that much. kidnapping is not an issue at all imo
