I'm no technology expert but I'm reading that the GPS location of where you caught a big fish - and then shared it on line - can be obtained thru the metedata in the photo, even when the location is 'hidden' by the person posting the photo. Apparently, there are apps that can 'data mine' even the hidden metadata. I'm also reading that there are apps available that can pinpoint the location where a photo was taken even without the metadata being available.

Is all this true? Are there folks out there mining metadata from images of photos that fellow anglers are sharing on line?? If so, I'm done sharing images on line!
