One reason I left Facebook early on was that I didn’t like getting tagged in photos the next morning after everyone would get home from parties. Too bad for me, as long as you have a friend who don’t value your privacy, there is nothing you can do about it.
Add to this any public event, where they are well within their rights to take your picture and match it against known threat actors and the only way to not play this game is to be a hermit
