The Immunity Syndrome:
Facebook Uses AI to Tackle Spam
Facebook uses artificial intelligence to monitor user clicks and prevent spam.
The Facebook Immunity System monitors up to 25 billion user actions per day.
From New Scientist:
One notable attack took place in April, says Tao Stein, a Facebook engineer who works on the system. It began when several users were duped into copying computer code into their browser's address bar. The code commandeered the person's Facebook account, and started sending chat messages to their friends saying things like "I just got a free iPad", along with a link where the friends could go to get their own. Friends who clicked on the link went to a site that encouraged them to paste the same code into their browsers, further spreading the plague. "Attacks like these can generate millions of messages per minute," says Stein.
