Facebook's massive identity database with linked photos would be useful for this service.
Is there a point where I would be recognizable to friends and family, and yet make algorithms choke?
And if there is, I wonder what would happen when my grandchildren are looking through old photoalbums, and wondering why Grandpa looks a little weird in all of his photos.
Edit: downvotes? FB provides law enforcement with step-by-step instructions on getting this information. https://www.eff.org/node/58178
