I wonder how labelling would work with news like saddam hussain's weapons of mass destruction - reported by cia, backed by the goverment as truth, but turns out it was all fake.
There's no need to talk technical about graph nodes and machine learning. It's very simple - the fake news labels are, and will always be biased in favor of the liberal/progressive/Democrat agenda. Objective news is a lie. No one wants to hear it. We want echo chambers that make us feel good. The labels will shift to accommodate this desire.
