#facebook is embedding tracking data inside photos you download.

I noticed a structural abnormality when looking at a hex dump of an image file from an unknown origin only to discover it contained what I now understand is an IPTC special instruction. Shocking level of tracking.. Image The take from this is that they can potentially track photos outside of their own platform with a disturbing level of precision about who originally uploaded the photo (and much more).
