Facebook shuts down 1 million accounts per day, says security chief

Facebook turns off more than 1 million accounts a day as it struggles to keep spam, fraud and hate speech off its platform, CNBC reports, citing the company’s chief security officer.
 
Still, the sheer number of interactions among its 2 billion global users means it can't catch all "threat actors," and it sometimes removes text posts and videos that it later finds didn't break Facebook rules, said Alex Stamos.

"When you're dealing with millions and millions of interactions, you can't create these rules and enforce them without (getting some) false positives," Stamos said during an onstage discussion at an event in San Francisco on Wednesday evening.

Stamos blamed the pure technical challenges in enforcing the company's rules — rather than the rules themselves — for the threatening and unsafe behavior that sometimes finds its way on to the site.
