This week, Facebook users across the country had a heart attack and grabbed their foil hats in horror for what they saw as an almost sci-fi Facebook feature they thought was. be slipped over them to enter them in the night: a list of phone numbers. As you may or may not know, Facebook has had your phone number since you first entered it when you signed up on the site. Didn’t you sign up with your phone number in the first place? Have you downloaded any type of Facebook app on any type of smartphone in the past? If you have, you have agreed to have your mobile phone number shared with all of your friends.
The only relatively new thing is the actual list of phone numbers. These numbers are available to you and your friends from several months now, but it is only since a few days that the torrent of REALIZATION has come out. You may have seen a post (or derivation in some way) like this permeating your Facebook news feed:
It’s true! ALL PHONE NUMBERS of your contacts are now on facebook! Go to the top right of the screen, click on ACCOUNT, click on EDIT FRIENDS, on the left of the screen and click on CONTACTS. You will see that ALL YOUR CELL PHONE PHONE NUMBERS (FB friends or not) have been posted. To delete, go to the right column under Directory Contacts and click on “THIS PAGE”. Please repost this on your status, so your friends can remove their numbers and avoid abuse if they don’t want them posted!
If you take care and follow the crazy person’s instructions above, you will actually delete the contacts you imported from your mobile device, at least Facebook would have you believe it. You’ll also need to go through a process (as shown in the image below) where you open your Facebook app and turn off sync. The instructions here tell you to do this with your iPhone app, but a similar process works for Android.
This large list of numbers you’ve seen isn’t public, or more public than each number on its own – if your friend has a profile with a publicly displayed phone number, it will be public regardless. everything YOU do. Note again that these numbers come from Facebook, not from your unconnected contact book, certainly not if your contacts are not connected to Facebook. Also, you might want to know that if you’ve ever typed your phone number anywhere on Facebook, it’s accessible, like Tom Scott’s classic webpage. “WRONG” shows quite clearly.
In short: the numbers come from the users who entered them themselves. No Facebook user to whom you have not given permission to see your number has access to your number. Protect yourself by not capturing information you want to keep secret by not posting it on the internet in the first place.
