Facebook scans the users' correspondence and automatically links the likes to the links

The unusual, if not to say doubtful, behavior was caught by the world's largest social network, which today boasted one billion users, security expert Ashkan Soltani - if in the user's personal messages there was a link to a Facebook fan page, then the network believes that the user favorably relates to the person or brand and automatically puts a “like” on it.

Actually, the problem was not in the very scanning of correspondence (Gmail does the same to show targeted ads), but that the network software arbitrarily makes decisions for the account owner, which may be different from a positive attitude towards someone or something -or. And since the user's “like” is visible by default to all his chronicles, his unusual or even strange tastes may raise questions with his friends and subscribers.

Here, for example, an extremely informative page created by Soltani, which was “liked” by more than three hundred people.

The following is curious - here , on Hacker News, someone posted a video in which he repeated the trick described above (we managed to get the test page up to 1,800 likes per hour), but as it turned out, this video contradicts the rules of YouTube and was removed by the administration of the service. Now it is posted by another user and is still available.
