We present some simple models to determine whether or not the accretion of
cold dark matter by supermassive black holes is astrophysically important.
Contrary to some claims in the literature, we show that supermassive black
holes cannot significantly alter a power law density cusp via accretion,
whether during mergers or in the steady state.
