Umm, are you sure about this one? It doesn't really seem to match the description, this only affects /kick (and even so, I'm not sure this would be the right way, since you're just removing the src parameter from the status_percent_change call, which most likely has have some side-effects). And what about the monsters killed by this player by normal means? I don't think I see code that disables those drops?
