What is a KO script on Roblox

game.Workspace.NAME.Head:remove()
game.Workspace.NAME.Torso:remove()
game.Workspace.NAME.Humanoid.Heath = 0
game.Workspace.NAME:remove()

simple loopkill script (breakable in some places)
-----------------------------------------------------------------------------------------------------
while true do wait(10) game.Workspace.VICTIM NAME.Torso:Remove() end while true do end

EDIT: This script only kills the person, if anything, and a REAL ko script that actually gives YOU the ko script no longer exists since the issue was patched.
