Ban

From the Dark RuneScape Wiki - follow the rules, or else!

A ban is a type of punishment that JaGeX may decide to issue to players who break the Rules of Conduct. When JaGeX discovers that a player has broken the rules through an abuse report (or other means), JaGeX may decide to give the player a penalty in the form of black marks. Depending on the magnitude of the violation committed, the player may receive a warning, a (possibly permanent) mute, or a (possibly permanent) ban. The player will receive a message in the message center on the RuneScape website informing them of the duration of the ban. However, It may be permanent. During this ban period, the player will not be able to log into RuneScape. If the player attempts to log into RuneScape, the player will receive a short message informing them Your account has been temporarily disabled. Please check your message center for details. Permanent bans are given to players who have exceeded the ten black mark limit. If appealed, first-time permanent bans may be lowered to permanent mutes.
