It really doesn't matter to me what you do -- heck your sites are yours, and if you get dinged in the future, and refuse to try to understand the complex reasons why this happens, that's your choice.
Like I said before - The QS is easy enough to manipulate. And if you think you know the complex reasons why this happens... you haven't a clue. You spend too much time in here defending google to know how it really works.
PS - If you don't like posts complaining about google - Then Why do you keep them alive?
