NO gravitons come OUT of the black hole. In contrast: only pushing and oscillating vacuum (Axion-Higgs) come IN ( llke the Casimir effect)

For a suggestion of the Solution of the Hawking Paradox: See the opposite article:

However, the Hawling Paradox is also denied by:  

The New Physics Black Hole Nucleus: Gravity Without Inertial Mass Effects and not dual opposing  but single pressure gravity.

Conclusion:  Ball Lightning black holes are evaporating. Large ones keep growing: Like Comets. Sunspots, and even Supernova Black Hole nuclei, only by eating the Axion-Higgs Vacuum.

Below: Dual pressure Gravity by  Gravitons countering Axions.

Left below: Black Hole single pressure Gravity from the Axion vacuum. No Graviton pressure reduction.
