Re: So...
Or, pretend that you're doing it to train AI's but in reality your TOS says that you own all the images people post on your social network site. So you mark them just in case that massive collection of images you own becomes valuable, or you decide to open your own stock image company. Better still, you tag each photo with an unique identifier so you can track it's progress and connections between people, somewhat like a cookie but inside the image files...the possibilities are endless for FB.
