    If light can orbit a black hole, and it is continuously coming in from every direction, wouldn't it get "crowded" in there over billions of years?

    Those orbits are not stable and the light will fall into the black hole as a result of even the tiniest gravitational disturbance. Since objects in the universe are always moving around, these disturbances happen constantly, so it never has a chance to build up.

    Light that is "coming into the black hole" will always spiral in. The only photons that could have a stable orbit are created (or reflected) at the orbital radius. Then what Drakkith said applies to that too.

    Yes it gets crowded and the result of that is a quasar

    The photonsphere of a black hole is merely an illusion. It has no physicality and is no more real than a rainbow.
