I saw a comment that is based on common misconseption and upvoted in to stratosphere (HNQ effect).
What should I do?
Posting a comment response seems futile (past HNQ effect, no matter how good my reponse is, 40+ upvotes on original comment means it will always be signaled as "correct" one, and mine will likely remain unseen below a long thread).
Flagging seems to rarely work when there's a purely content correctedness dispute on most SEs, as the flags like that are frequently declined as "only flag things that require moderator attention".
