Slightly related, but I once ran an imageboard for friends and set up a hook to output the EXIF geolocation of uploaded photos to a private IRC channel.

It was surprising to see how often something would show up! Even when uploading photos straight from a phone through the browser.

There's a lot of things that strip the info now before it goes to server. Photo apps themselves, image boards etc.

Far bigger leaker is MS Office or pdf metadata. Heck, they even catches that famous serial killer who took creepy pictures of himself in women underwear because eventually he started sending files, not regular letters, to police taunting them.

Edit: BTK was this sick man's nickname. Busted by having his church's computer metadata in files to police https://www.bizarrepedia.com/btk/

WARNING about the crime scene photos of the serial killers murders in that link. Would have preferred to have not seen them right before bed.

This just shows how poorly software that captures the images and adds geolocation without user knowing is made.
