So I thought it'd be a cool privacy feature for Mastodon to automatically strip EXIF metadata from photos (e.g. GPS latlong, date, etc.). Turns out Eugen already thought of that! 😁 https://github.com/tootsuite/mastodon/issues/85
I even checked some uploaded photos with ImageMagick; they're all empty! BTW here's the EXIF data from a typical photo I took on my Nexus 5X. I really did have to make the text that small to fit.
