Hah! So also in Anatham, there are other machines that do this. The design the author wrote into the story involved two species of machines that work at full speed with 100% uptime to both revise and tweak the facts of a story and then, separately, to assign grades. Basically a world-wide generative adversarial network.

From the attacker's point-of-view, in order to deliver a false message they are forced to try to fight through a gauntlet of independent machinery that will first generate a bunch of alternatives and then will look at any particular story and assign a grade with knowledge that it's probably being attacked. That could be a very tough filter to consistently navigate, especially if our attacker is trying to conduct a broad campaign of misinformation.

From the victim's point-of-view, every piece of information they read now is associated with a score provided by their fact checking filters -- and there is no reason not to have multiple layers of grading filters.
