> similar to how Youtube handles copyright claims This is a practical suggestion, but not one I find reassuring. The Youtube copyright system works fairly well from the perspective of big rights holders, but is relentlessly abused for both censorship and corporate overreach in taking down fair-use or even non-infringing content. That's basically the outcome I expect from a fake-news-takedown system, too. It would almost inevitably end up working for whoever was willing to throw the most time and money at manipulating content.
