Facebook uses your phone number to target ads
In an honest admission, Facebook has said that the phone numbers that its users provide for security purposes are indeed used to target them with ads. This was always suspected.
"We use the information people provide to offer a better, more personalised experience on Facebook, including ads," the company's spokesperson has said.
"We are clear about how we use the information we collect, including the contact information that people upload or add to their own accounts. You can manage and delete the contact information you've uploaded at any time," the statement adds.
A University study in the West has described the phenomenon as "shadow contact information" to make money.
