Looking at the rejected comments makes me wonder: would it make sense to only allow new users to comment on articles less than 7 days old? Then their comments would be seen by most users. As opposed to commenting on old articles, where it is more likely to be seen by either moderators or no one.
Recent comments appear in the “Recent Discussion” section of the front page, regardless of post age. Not sure how many people use this feature, but I like it as a way to follow longer-term ongoing discussions after I’ve hidden the post itself or it has fallen off the top of the “Latest Posts” section.
So I do occasionally see comments from new users on much older posts. The quality varies, but I’m not sure that there’s any correlation between post age and new-user comment quality that would make a rule like this worth implementing.
