Please don't spread false info. You just create paranoia which leads to useless threads.
I said advise, I didn't say "should". This is not false info, precautionary action is never false. I don't see why you are being a dickhead, it was an opinion. It's almost always better to do a clean installation regardless, if I'm not mistaken? So to put it bluntly, you're useless post just made what I said sound bad.
