I suggest we add a KOS command that is similar in functionality to the DOS command. To avoid abuse, perhaps only certain LF can place KOS on revealed DF. 

Some benefits to this addition:

• KOS is automatically removed when the DF dies or is killed
  
• Allows LF to easily tell when someone is KOS without remembering one OP message
  

Some drawbacks to this addition

• Could be somewhat difficult to add and maintain as DOS system
  
• More jobs will be able to place these kinds of server-wide things on other players
