For years I’ve gone back and forth over the practice of obscuring license plates on photos on the internet. License plates are already publicly-viewable things, so what’s the point in obscuring them, right? Well, now I think there actually is a good reason to obscure your license plates in photos because it appears that Google and Facebook are actually reading the plates in photos, and then making the actual license plate alphanumeric sequence searchable. I tested it. It works.
