>should be continuously running simulations that are constantly fed fresh TLEs from tracking stations, that check whether or not anything is going to collide I'm ready to bet that they do this already, and that collision detection is automated indeed. However given the very high cost of orbital maneuvers (can't refuel a sat, so there's a limited quantity of delta v corrections you can do) there's probably a backlog of possible collisions to be checked and acted on manually. The ops team gets to it when they get to it.
