@Alfred when asked to identify where a picture was taken, are you using exif data embedded in images?
I can answer this very AUTHORITATIVELY in two ways, mostly because I was there when I built this place.
1). Any image uploaded to COSO has all the Meta/EXIF data stripped from it at our edge, before it even lands on our media storage array.
2). When he's trying to identify where an image was taken, it's purely visual, pixel by pixel, not reverse image searches and not EXIF (because there is none. See above).

@th3j35t3r @stuartblair @Alfred I figured that was the case. It's very impressive.
