The MOTD doesn't contain KOS rules and what happens when you do it. I know alot of the rules but I didn't know that calling a KOS jokingly or not on a D then you get slain. I would just appreciate if that was up there same with all other KOS consequences because it's not up there to my knowledge.
I'm pretty sure calling a KoS on a D is just false KoS. The Mod who slain you should've warned you the 1st time and slain you the 2nd.
