The matter is ejected from outside of the event horizon where the escape velocity is less than the speed of light.
Black holes also emit hawking radiation

I'm not sure what causes the expulsion from the accretion disk myself. It should be noted that the ejection comes from outside what is normally defined as the black hole.
Hawking radiation is different to black body radiation because it it proportional to the mass of the hole rather than the temperature.

That's exactly what i was saying..it doesn't seem to be logical does it?
It's ever present (even when consuming at it's maximum rate) super gravity, strong enough, even to prevent the escape of photons, continues to attract - yet somehow, it ejects the excess matter with unbelievably force.

By 'not sure' with regards to accretion disk expulsions I meant that it is possible there are other effects taking place as can be seen with pulsars and grb's. As deceived in bearmans post however it seems they are now quite sure.
What you stated about blackbody radiation is correct but even so blackbody is defined by temperature and hawkings by mass hence the different name.

So it doesn't matter about hawking radiation it still should be called black body radiation.

I will pass on your recommendation to ISO...
