[http://www.wurmonline.com/forum/viewtopic.php?t=7814 Theft, PVP, and other kinds of griefing] are frowned upon, and are bannable offences in many instances. In addition, stealing and PVP typically result in loss of [[reputation]]. As reputation drops, the player becomes an [[outlaw]] and eventually a [[blacklighter]]. At this point, the player is kicked off the server into the wild.
As an notable exception to the above, inter-settlement [[settlements#Wars|war]] is possible. However, both sides of the conflict are required to accept the declaration. It is not possible to wage war on a target who refuses to participate.
[[GM]]s will police these servers as needed, but ideally the game rules should take care of things automatically. [[Moderator]]s police the kingdom chat channels to ensure the chat rules are followed.
