What? First of all, there is no rules against spawn killing. Second of all, there is no need to have a rule against it, as there is an auto-jail system if you kill the same person one too many times. Tres de el mundo, when you are killed, you should be re-spawning at /spawn, so you would have to deliberately be going back to the place you were just killed at, (and if your killer is still there, common sense says that they will most likely kill you again).

Also it’s best to bring proofscreenshots/video so it doesn’t seem like you’re whining, rather reporting. Otherwise, the response may be as limited as the information provided.
