In a new development, Facebook has confirmed the news that users’ phone numbers shared over the social network were shared with Advertisers. Moreover, the phone numbers which were shared with Facebook for two-factor authentication were also used by the platform for advertising purpose.
This two-factor authentication purpose is also used for second step of attaining security, such as passwords for getting into old accounts.
As per researchers, “These findings hold despite all the relevant privacy controls on our test accounts being set to their most private settings.”
In addition, study has found out that the contact list which has been uploaded on the Facebook platform could also be exchanged for your personal information. This implies that you as a member may be assisting these advertisers targeting your friends.
Researchers also revealed, “Most worrisome, we found that phone numbers uploaded as part of syncing contacts — that were never owned by a user and never listed on their account – were in fact used to enable PII-based advertising.”
A spokesperson also said, “We use the information people provide to offer a better, more personalized experience on Facebook, including ads,” “”We are clear about how we use the information we collect, including the contact information that people upload or add to their own accounts.”
These revelations have added to Facebook’s woes and it can lead to a loss of many loyal members.
