New privacy issue on Facebook. This time, the largest social network seems to be "getting its hands on" its members' mobile phone numbers, which are provided solely for two-factor authentication, not targeted ads.
Of course, those of you who have given your Facebook number thought that it would only be used for two-factor authentication. Wrong Facebook uses numbers to connect with other people and target everyone with online ads.
For example, if someone you know, give his Facebook number and allow Facebook to access his smartphone's contacts, the application reads all his contacts (do you think he does not save them?). So it can connect you with some, and it will keep you connected even if there is a rupture in your relationships.
Of course, Facebook does not stop at promoting targeted ads, but also gives your number in its search function σελίδαs.
The outbreak of slogging on Facebook's phone number was triggered on Friday by Emojipedia founder Jeremy Burge, who publicly criticized Mark Zuckerberg's information gathering and user search through Facebook phone number for account security purposes only .
"For years Facebook claimed that adding a phone number was for 2FA and only for security." he said through his Twitter. "Now they find you in the searches and there is no way to turn it off."
Facebook has partially disabled similar phone number searches in the past, preventing someone from looking for their profile number. Today Facebook seems to re-use the numbers in searches on certain accounts, and undoubtedly uses WhatsApp searches for numbers.
As explains Facebook to one support page, uses account security phone numbers to help your friends find you and some possible recovery of your account.
It does not mention using phone numbers for advertising. Researchers from Princeton University and Northeastern University on USA last year they looked into how Facebook uses personally identifiable information provided by users.
They found (PDF) “that phone numbers and email addresses added as profile features for security purposes, such as two-factor authentication, those numbers provided to the Facebook Messenger app for the purpose of respondingchange messages, but also numbers included in users' contacts, are used by Facebook to allow advertisers to target users."
According to Alex Stamos, a former Facebook security chief, the social network was planning to separate the phone numbers used for 2FA from other phone numbers given for other purposes, but that is no longer the case.

Good Evening. Nice article!
I wanted to ask the following: My fb "blocked" my account and asked for a phone number to send me a password. Of course I do not want to give my number.
Is there anything I can do?
