X-Rays and gravity wobbles. I mean, Black holes are detectable. We know where some are. Just because they don't emit light from their event horizon doesn't mean they are somehow now invisible. There are plenty of high-energy X rays emitted from interactions on this side of a black hole's event horizon that we can see.
Besides, we can now even see the effects of a small planet on a star's wobble. I think if a black hole was eating away at a star - one that we have been looking at pretty seriously ever since we noticed the weirdness - we would be able to detect the wobble that a Black Hole eating a star would cause.
