Just dropping this in here:

rule 2.1 Random Death Match
Players are not allowed to kill others without a justifiable reason. Random Death Match or RDM is the act of killing without a justifiable/valid reason and is punishable. It is required to ask a player who killed an innocent why they did so, unless you can be certain that they did not have a valid reason. Without a justifiable, or believable reason they can be killed. Read rules 2.6 and 2.7 for more information on when killing people is acceptable.
