Add “a phone number I never gave Facebook for targeted advertising” to the list of deceptive and invasive ways Facebook makes money off your personal information. Contrary to user expectations and Facebook representatives’ own previous statements, the company has been using contact information that users explicitly provided for security purposes – or that users never provided at all – for targeted advertising.
A group of academic researchers from Northeastern University and Princeton University, along with Gizmodo reporters, have used real-world tests to demonstrate how Facebook’s latest deceptive practice works. They found that Facebook harvests user phone numbers for targeted advertising in two disturbing ways: two-factor authentication (2FA) phone numbers, and “shadow” contact information.
