Guild Wars Wiki:No More Screwing Around

Admins may exercise their own discretion against those who clearly and willfully act against the best interests of the wiki. An admin may act as necessary to prevent users from purposely disrupting the wiki, including removing content from talk pages and user pages, issuing warnings, and, if warnings are ignored, issuing bans.

Enforcement
As always, banning a user should only be used if there is no other way to deal with the unacceptable behavior. However, if the user has been warned and continues their disruptive behavior, an admin may ban for a length of time appropriate to the offense. If the user has previously been banned, each successive ban should be longer than the last, up to and including banning the user indefinitely.
