Snoopy relatives of women I have dated a couple times, a couple times by PIs paid to track me down, and a stalker once.

So...yeah. It's a real problem and none of these people had a legitimate cause to do so. Even beyond FB, etc. I don't post my face online because of shit like that.

Other people have stopped posting pics of me as well, a couple people have been called based on my name being tagged to things on social media.
