Do black holes swallow dark matter?

We know dark matter is only strongly affected by gravity but has mass- do black holes interact with dark matter? Could a black hole swallow dark matter and become more massive?

We don't really know what dark matter is.

The prevailing hypothesis is that it's some kind of particle that only interacts gravitationally (well, for the most part). If that's the case, then yes, black holes should definitely be able to swallow that stuff up.

Under that same assumption, it should be noted that dark matter will probably not form an accretion disk, nor would it care about an existing accretion disk. So dark matter particles would just describe conic curves around the black hole. If the curves happen to intersect the event horizon, the particles will be captured. Otherwise no capture will occur. (with some corrections to those trajectories due to general relativity)

If it turns out that dark matter is not particulate stuff, then all of the above does not apply.
