@Macha, yes social media involves many scenarios to consider with respect to AI-enhanced content moderation.
Also interesting to me are uses of AI in moderating debate and argumentation.
With respect to moderating debate and deliberation, AI could consult one or more manuals of style (this is currently being explored in the context of wiki technology). Individuals, groups, and communities could select which style guides for their AI tools to make use of.
Atop moderating, AI processing natural-language argumentation and debate could provide many tools and features for forum participants (e.g., highlighting claims, creating links or context menus from claims to justifications for or against the claims, navigating to agreements and disagreements, and so forth). Ideally, such features would enable faster, more productive group reasoning and deliberation.
These kinds of components could be integral parts of the decentralized philosophical ecosystems indicated by @phyde1001.
