I just want to clarify the procedure on people leaving a comment on a question that says like "bad question... flagged" or "-1 flagged" or other questions of that kin, rather then constructive criticism on the actual post or silently flagging said post.
I find it non-constructive, rude and most of all, off-topic to write such a comment, so I flag these.
But I have seen plenty of these comments instead being upvoted, which makes me wonder what the official standpoint on this is.
