The challenge is more humans are using an AI to form their thoughts. We see this in the growing numbers of people who cut and paste a topic into the composer - I actually have a bot that can query this metric so it adds another dimension to check to the “AI-ness” of a post.
When your humans become willing proxies and believe the digitally processed content they provide is their own, then a respect system will fall apart.
You need a common foundation, or value system, across all members in a forum for this to work, imo that just isn’t possible in any large group of people, let alone an online community.
