We already know the drill for proving we are not bots: simple math, a second email, or, worst case, a phone number. Facebook is adding another ask. Soon it may request a clear face photo to show that an account belongs to a real person.
With more than two billion users globally, Facebook wants the photo check for suspicious moves across the product: creating accounts, sending friend requests, setting up ad payments, and similar edits. Uniqueness of the photo helps decide whether an account looks genuine.
The company frames the photo test as one of several automated and manual tools for catching abuse. Privacy tradeoffs inside its own ecosystem are already stiff. Keeping the platform safer may keep pushing those tradeoffs further.
