You can never "turn back" your digital footprint. Its there forever to be exploited and pimped like a cheap whore by the "progressive" social media powers that be. You can "turn back" or mitigate any future footprint you leave, but whats there is there. Im not in the bus. but have friends who are and have some businesses of my own that dabble in it for their own marketing purposes, and I can tell you, Facebook and Google (read Android phones) etc., theyre all tied into the credit reporting agencies and credit card companies and banking system and all that. Im not an apocalyptic bomb shelter type person or anything of the sort.... but trust me its true and its the world we live in now and increasingly will be. How does this commentary relate or belong at all in this great RS6 forum???..... thankfully I likely won't be around to see this human identity surrendered for marketable digital identity phenomenon fully take hold..... and as long as I can keep all my old skool rides - very much including my beloved and quirky RS6 - running and making me smile... everything will be ok. And I don't think Ingolstadt put a GPS / DNA tracking chip in my '03 RS6.... read = valuable car getting more valuable by the day.
