A cautionary tale, that what exists in the wilds of the web is never personally retained, and cannot be.
And, no, TK, you can't delete your Facebook or Google or Amazon profiles. You can theoretically adjust publicly available settings, but each of the social media/big data giants retain all your data and info, forever. It all gets fed into their metadata algorithms; it is used to "fill gaps" in data that they are able to assess and determine, though such data has never been disclosed or given; all such determined data rests within their sole powers as well; with no access, identification, or control, of or by the TARGET: YOU.
