It would make a lot more sense - and probably be easier - to fix social norms to recognize that people change, and that old comments from the person you used to be aren't from the person you are now. I would assume that this will happen on it's own, as people grow up with exposure to their own permanent record and notice that they don't recognize their old selves.
