On Tuesday, Facebook said it took action on some 2.5 million hateful pieces of content in the first three months of 2018, up from 1.6 million in the last three months of 2017.
In the first quarter, the company took down 837 million pieces of spam, almost 100 percent of which was found and flagged before anyone reported it.

The problem with trying to proactively scour Facebook for hate speech is that the company's AI can only understand so much at the moment.
"AI still needs to get better before we can use it to effectively remove more linguistically nuanced issues like hate speech in different languages, but we're working on it", said Zuckerberg to CNet. "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".
