[hmnpddbv] Dark matter versus black hole

What happens when a black hole plows through a cloud of WIMP dark matter?  Dark matter is assumed to be able to pass through most things, but not a black hole: the black hole must gain some mass of the dark matter the falls directly in.

Will an accretion disc form?  Can accreting dark matter lose angular momentum by friction, so eventually fall in?
