You are aware that the Spirit World and Physical World aren't always buddy-buddy. Hei Bai was only able to come out at night, and that was in the couple weeks before the Solstice, the most spiritual time of the year, and where he came just so happened to be apart of his own physical realm (being the burned down forest). The two most powerful spirits we know of gave up their spiritual form to become...fish. Although La kicked some butt with Aang, their spiritual forms went into the physical world only in the place where they can have substance, the Northern Water tribe.

It would be rather difficult for a spirit, one who's powers include stealing faces and having a vast array of knowledge, to come into the physical realm as a normal human being in such a non-spiritual time, not show off anything that seems non-human (e.g. turning into a giant centipede), and steal bending from people.

Also, the point comes up that he has no reason to terrorize the mortal world due to lessening of spirituality. I'm sure he'd be happy if the spirit world and mortal world were cut off from each other so the Avatar wouldn't mess with him anymore (remember Kuruk?).
