Well, here's the thing; right now Facebook, Google, Microsoft and a large number of Advertisers have a shadow profile for someone who very well might be you, if you provide information about yourself on Facebook or the like at least you get to set your own record rather than say having someone who doesn't like you tag your name onto a bunch of things that don't belong to you.
So, either you ensure that no one that ever knew you posts things about you online or you get on top of it and make sure your "public profile" is "correct".
In a way we've just started moving back into the small town/settlement mode where everyone knows everyone else and what's going on around "town".
