I was pretty confident that comments with "didn't downvote" statements should be removed. Well, I flagged such a comment as "Didn't downvote statement", but it got declined.
Probably because of the criticism that was also in that comment. Should I refrain from flagging "didn't downvote" comments if they came with constructive criticism?
Apologies, but I did neglect to acknowledge that the constructive criticism was indeed outdated, so flagging as "No longer needed" was the key. I didn't know that at the time.
