Yeah. I think hacker news has some decent ideas about how to manage these things. You can ask chat gpt about some details to get the idea, but I think its something along the lines of users not being able to affect a discussion with voting until they have some sort of reputation. And I believe that reputation has to come from reactions by the community.
I think if you ask chat gpt about that and have a discussion, some good ideas could surface. They have karma but it's a ladder system where users get more options only after contributing successfully to the community, not just by time.
