Facebook removed 837 million instances of spam from its website in the first quarter of 2018, according to Guy Rosen, the company's vice president of product management.
Between October 2017 and March 2018, Facebook took down content including graphic violence, adult nudity and sexual activity, terrorist propaganda, hate speech, spam, and fake accounts.
In addition to deleting spam, Facebook disabled 583 million fake accounts. Facebook estimates about 3 to 4 percent of its active accounts were still fake in the first quarter. The company also scrubbed 21 million pieces of adult nudity and sexual activity, and 3.5 million pieces of violent content from its platform in the first quarter of 2018.
Facebook estimates it removed 2.5 million instances of hate speech in the first quarter of 2018. "For hate speech, our technology still doesn't work that well and so it needs to be checked by our review teams," according to Mr. Rosen.
He added, "As [Facebook CEO] Mark Zuckerberg said at F8, we have a lot of work still to do to prevent abuse. It's partly that technology like artificial intelligence, while promising, is still years away from being effective for most bad content because context is so important."
