Do anyone know. For something to truly spin it has to have a radius, and anything with radius that spins has to have angular momentum right?
Can angular momentum of a black holes be measured?
Also, is the event horizon or space above the event horizon spinning?

While the mass of a black hole can take any positive value, the charge and angular momentum are constrained by the mass. In Planck units, the total electric charge Q and the total angular momentum J are expected to satisfy this equation:
(q^2)+(J/M)^2
where M is the mass of the black hole
and yes the event horizon above a black hole is spinning so thats why you sometimes get visible 'jets' of matter shooting out from the poles of black holes but these usually only happen in supermassive black holes that are feeding...
