It's very hard for humans, much less algorithms, to <i>quickly</i> distinguish marginalized speech of the legitimate, unpopular, thought-leading, high-integrity from conspiracy theorist, utopian, pipe-dream, violence-advocating, mystical nonsense <i>without a deep evaluation of a large sample of content, including understanding satire, snark and comedy.</i> Jimmy Dore, Chris Hedges, Phil Donahue come to mind as marginalized, reliable sources.<p>Maybe some obvious topics can be blacklisted if they're repeatedly, seriously mentioned like chemtrails, anti-fluoridation, anti-vaxx, zero-point energy, pizzagate and antisemitic conspiracy theories... and an appeal for those who get caught up in a comedy refrain.
