Yeah, I was tagging plagiarists for a brief period of time, but I stopped doing it because I figured it was a waste of time if the plagiarists were going to get banned anyway. 

Let me correct the "unwarranted" statement.  The feedback itself is appropriate.  It just isn't necessary.  That's what I should have written.  I am in no way criticizing you for negging this guy, because I wouldn't trust him either.
