The discussion of moderation policies and topics in posting usually derive from a shared understanding of a forum as a group of people, rather than a trajectory where current community opinions in turn, create the future community.

There is also the origins of Hacker News as Startup News, which immediately creates a covariance constraint between seniority and topic. The only way this dynamism can be managed is having temporal aspects (e.g., boundaries, limits on accelerationism toward specific topics), included in moderating policies.
