Space pirates' ultimate version of walking the plank would be sending their victims into a black hole

Why waste time and fuel going all the way to the location of a black hole (not to mention that all the radiation near it isn't going to be good for the ship) plust the delta-V to reduce their speed until they actually are not in orbit anymore and fall down into it?

Best just jettison them out of the airlock without a suit in the middle of nowhere.
