The outcome of the discussion on this post, Should 'Hi', 'thanks,' taglines, and salutations be removed from posts?, was that the salutations/greetings should be editing out from a post by the editor of that post. But I guess that was applicable only if the editor was editing the question to make it better and happened to run by the salutations, thereby removing them.
Contrary to my thinking, a fine user on SO has taken this too seriously and has started editing out only salutations/greetings from any question he/she comes across, very nicely stating the above mentioned meta post as a reason for the edits.
Removed "XXX" text. Avoid salutations (Should 'Hi', 'thanks', taglines, and salutations be removed from posts?)
And I'm not sure if it is the robo-reviewers or normal reviewers, but most of those edits have been approved. Below are a few suggested edits by that user giving the meta post discussion link as the reason.
Is such a behavior acceptable where the OP can just cite a Meta post and abuse the editing feature? Can we do something to stop this behavior, not just with this user?
