It appears no one's thrilled facial recognition upstart Clearview is scraping their photos to build a facial recognition database to sell to cops. But what can they do about it? Not much more than write angry letters.

Twitter was the first to send a C&D to the troubling developer over this troubling development. It was presumably ignored. Google also issued a C&D, only to be not-so-gently reminded by Clearview that Google does the same thing to build its search engine database. (Of course, web site owners and developers can opt out of being crawled by Google bots -- something that's not an option with Clearview.)
