There is a simple solution to the AI spam issue (and spam in general) - a social trust graph at the heart of content aggregation and discovery. Associate all content with real humans and allow people to control their level of trust in other humans, then derive a trust score for content based on a weighted combination of your trust of the creator and the trust your friends put in the creator. When bad content shows up as trusted for a user and they "corrects" the system, that correction backpropagates trust penalties through the social graph. By allowing people to see when they lose trust, it creates a feedback loop that disincentivizes sharing/trusting garbage to preserve social trust.
