My job requires daily public interaction I have encountered people at work that I recognize their face but I don't know who they are. Then I look at their ID and realize I know them from things they've posted on Facebook. It's happened more than once.
I make a point of keeping any identifiable pictures of me off the internet
Me & Granddaughters a couple of years ago
And me a long time ago
Remember, I've mentioned being a redhead. There is the proof.
Yes, it is colored now days but not back then! I was about 25 in the long haired picture.
