Facebook generated email addresses to all users
Facebook in its style took and replaced in the profiles (timelines) of users all the addresses of third-party mail services, such as gmail.com or mail.ru, with their addresses in the facebook.com domain. Who previously did not have a facebook.com email address - the system automatically generated it and made it the main one. The previous e-mail address has gone to the depths of the site and is not shown as contact information.
It turns out that it is very simple - change the postal addresses of several hundred million people. The main thing is to act boldly and decisively.
Facebook launched its own mail service in 2010, but it never gained much popularity. In April, the company synchronized email addresses with the timeline, so that the email address of the username @ facebook.com always matches the URL of the personal page facebook.com/username .
“As announced in April, we updated Facebook addresses to make them consistent throughout our website,” said a social network official. “Each user received an email address, and a new item appeared in the service settings where you can specify which email address you want to use in your timeline.”

You can return your email address in the profile settings ( instructions ).
UPD. Since in the comments many users do not understand the seriousness of the situation, it requires a little explanation. Some experts call Facebook similar actions an attack like MITM . In cryptography, MITM (man in the middle) is a method of compromising a communication channel, in which a hacker, having connected to a channel between contractors, actively interferes with the transfer protocol, deleting, distorting information, or imposing false. Imagine a situation that User A wants to send important information to User B. To do this, he must go to User B’s profile, get information about his mailbox P - and send the information there. However, agent F secretly intervenes in the communication channel, who changes the value of P in advance in order to get a copy of the information to his server. As a result, the information goes to the server of agent F, but does not go to the mailbox P.
