Comments are given more importance on our site than other sites.The reason I say this is posts asking "Why my comments are deleted?" remain hot for more days than the posts which invite discussion and constructive input on the site. Moderators are also a bit more careful and take time when it comes to comment flags. From my experience, they are not quick and aggressive while removing some out dated or irrelevant comments under posts (No offense intended).
So, comments are sometimes used to answer, sometimes to give a link of the direct scripture itself, give information about the answer or question. When this information exchange takes place, there are some cases where comments are also posted which give misleading information. They are totally wrong. They contradict correct answers given to the same question. The problem is these comments are also upvoted and highlighted over other comments.
The reason I say they are problematic:
If you have taken look at the featured tab to the right side, there are many efforts put by Stack Overflow team to make the network user friendly and there are changes made to moderation and the Code of Conduct too. In one of those posts, Tim Post, a Community Manager based on some research pointed out that the comments posted under the questions are getting more focus. So, they wrote a post about improving the language used while addressing people in comments. As a result, there are changes in Code of Conduct and addition of Unfriendly/unkind language.
When we look at this in a different way, this means that the users read questions and their sight is attracted towards upvoted comments. When there are upvoted comments posted under a question are giving wrong information which contradicts given answers, that will definitely give a wrong information to the readers of the site (Our traffic is also very good. So, that would be a problem if we are providing wrong information even if it is in comments). These comments can't be downvoted to make them less focused like the answers. We can't perform moderation activities (like editing anytime to correct the mistake) like we do on posts. Only thing we can do is to refute the information given in the comment which may or may not receive the same response as first comment did. So, it only increases noise under the post but doesn't help the readers to conclude what is right is what is wrong. Some ask clarifications but most of the traffic is from anonymous users who can't post comments.
Other case here is posting comments based on false assumptions. There are also some comments posted which make accusations along with assumptions. These are sometimes unfriendly and impolite. For example,
@username, why did you downvote my post? You can comment without downvoting my post. Reverse it.
You have removed my close vote @moderator! It is not fair at all. You are behaving as if this is your own site.
In my opinion, these are based on guessing and false assumptions. We don't know who voted on our questions. As far as I know, moderators can't remove close votes on a post. They can only cast a binding vote for closing, reopening or in the review. Aging away of the votes is a system process. It is not only unfriendly but also conversational and more suitable for chat rooms. There are changes to the comment flags to reflect this. So, we should be careful about the language and tone too.
So, what do we do about the comments which give wrong and misleading information and posted on wrong assumptions? Should we flag them for intervention or let them as they are?
When I say wrong, I don't mean philosophically related topics where there is difference of opinions but the comments which are contradictory to the upvoted correct answers given and give misleading information about the topic. I am not talking about the ones which are asking clarifications about the correctness of the post and pointing out the wrong information given in the post. For example, Rama is the youngest son of Dasharatha. Even if there are some analyses about this claim, comments are not the correct place to put those analyses. Questions and answers are right place to do and enlighten the users.
I know wrong and right are subjective but when I say right answers,I am speaking of free and fair way of voting based on quality content itself i.e., "Best answers are voted to Top" from Stack Exchange Tour and not when everything is rigged and biased. We can counter it on questions and answers by votes but there is no way to handle it for comments. This post is reducing that effect upto some extent in comments.
