What is often overloked is how much location data leaks through photo metadata alone. Every photo taken with a phone contains GPS coordinates, timestamps, and device info in the EXIF data. People share photos publicly without realizing they are broadcasting their exact location history. At least with geofence warrants there is a legal process, with photo metadata it is just frely available to anyone who checks.
Most (all?) services people use to share their images strip the metadata. You’re not going to find exif data on WhatsApp, instagram, Snapchat etc
