We haven't crossed that point, for the simple reason the resources and manpower to do it sustainably don't exist. When you are dealing with hundreds of millions of people do the math on how many "arbiters of truth" you need. And AI/ML models can't keep up with the speed at which things change day to day. Rumors for a while have been they are moving to a different model where they control reach and speed at which content moves. Anything going viral "too fast" is automatically slowed down. That reduces dependence on determining type of content. Things will prob settle on some hybrid model down the road.
