@luna In a digital safety course for kids we show a video back from the days when big social media networks did not strip metadata on upload.

In the video, the camera person approaches seemingly random people on the street whose current location they extracted from the metadata in posted pictures. The interviewer then asks personal questions derived from the profile or the location metadata like "how was your last holiday in ...? Your name is ..., isn't it?" and at one person "You work at <secret agency>, don't you?" You can visibly see the shock in the face of the people, especially the secret agent.
