It's a mistake to think that checking a box that says "CC" means you actually had permission to issue a license.
If you're selling stock photos, you need written consent for everything in the photo--artwork, brands, people. Interestingly, parents can give consent for their kids to be in a photograph, but these same identifiers can be used years later to identify the adults in the photos.
A related question is this: do pre-trained classifiers reveal any personally-identifying information? Or are they only statistics about many, many faces?
