"When I got back from a trip I took abroad with my family earlier this year, my friends mentioned that they'd seen the photos that "I" had posted to Facebook. Except... I hadn't posted any photos to Facebook. I have a Facebook account, but I deliberately have a very minimal presence on it. What my friends were seeing was the photos that my mother had posted, and which I had been tagged in. My privacy was violated by someone else's inability to understand Facebook's privacy settings."

Ironically, it was your OWN inability to understand Facebook's privacy settings.

Go to Settings -> Click " Timeline and Tagging Settings" -> Edit " Who can add things to my timeline? " section : " Review posts that friends tag you in before they appear on your Timeline?" make " Enabled "

There, you will never be tagged in another photo or post, and you now have a review process for anyone who attempts those things, so you can manually up or down those things.
