A central problem in all online communities that this post doesn't address is the definition of malicious behavior. E.g. a forum run by the marketing division of Coca-Cola might define comments on the negative health effects of soda consumption or just how great Pepsi is as malicious behavior. Explicit definitions of malicious behavior in the forum guidelines may or may not be enforced if the forum is controlled by interests seeking to covertly amplify certain narratives while suppressing others, even if those narratives do not explicitly conflict with site guidelines. One plausible approach to this situation is to use a LLM agent as the forum moderator - one which only uses a publicly-available explicit set of moderation rules to flag comments and submissions. Something like this is almost certainly being used at Youtube, X, etc., with the caveat that the rules being used are mostly hidden from the public (e.g. X feeds don't seem to have much interest in amplifying stories about UAW's efforts to unionize Tesla, etc.). This could lead to a regulatory approach to social media in which the moderation rules being fed to the LLM must be made publicly available.
