It is occasional practice of some users to place message along the lines
CLOSE VOTERS: please don't close this as duplicate because it is not because A,B,C.
My question is this: Are we OK with such approach ? I personally find that these types of edits are more harmful (to questions) than not for the following reasons:
misleading reviewers: those who don't do reviews carefully and look at the context of the post and don't notice who placed the message into the question, may be lead to believe that this is OP's own statement, which in fact is one user's personal opinion , and personal opinions (if I understand correctly) should be kept within comments.
imposing one particular user's personal opinion on others: Goes along with what I said in the last sentence of previous point.Voting to close a question should be a personal decision or at least consensus with other users from a discussion and discussions should be kept in comments
No improvement to question: if message to close voters is the only thing that is being inserted into the question, there seems to be no improvement to the question itself ( which is what is the main purpose of editing, no ? )
opinion of one outweighing consensus of many: reviewers who see personal opinion of one user injected into the post may not notice discussion in the comments where multiple users might agree that post is in-fact a duplicate.
I understand the sympathy with having a question closed: users think that question visibility will be gone, but questions can be voted to be reopen as well. It is my personal understanding that voting should not be influenced by particular user's opinions.
Over time I've come to see that using pathos when dealing with close-votes isn't the best approach, and in-fact can do more harm than good to the question.
