Facebook disabled nearly 1.3 billion「fake」accounts over the past two quarters, many of them bots with the intent of spreading spam or conducting illicit activities such as scams, the company said on Monday … Most of the accounts were disabled within minutes of registration, Facebook claimed in a blog post, but Facebook doesn’t catch all fake accounts … Facebook says it finds most of the accounts on its own using software algorithms, but a small percentage — about 1.5 percent of the disabled accounts — were discovered after they were flagged by Facebook users.
