I manage a lot of spaces on Facebook and they recently'ish added a feature like this that moderators can enable on posts. It limits users to one comment every 5 minutes. It makes a difference - a big one. Some posts that would not have been approved end up being approved when this feature is enabled. Instead of wars of words and knee-jerk reactions, people know they can only leave one post every five minutes, so the first few replies take a few minutes to appear. Then, responses to those responses are even more cautious. People avoid commenting on multiple threads because they can't interact with all of them at once.
