Facebook is planning to request a "clear photo of your face" on pain of lockout, reports Wired's Nitasha Tiku. It wants you to prove you are a real engagement node, not a bot.

In a statement to WIRED, a Facebook spokesperson said the photo test is intended to "help us catch suspicious activity at various points of interaction on the site, including creating an account, sending Friend requests, setting up ads payments, and creating or editing ads."

The process is automated, including identifying suspicious activity and checking the photo. To determine if the account is authentic, Facebook looks at whether the photo is unique. The Facebook spokesperson said the photo test is one of several methods, both automated and manual, used to detect suspicious activity.
