Facebook will hire 3,000 people to review footage uploaded on the social media after videos appeared of brutal murders.
The new roles will support some 4,500 already employed to identify crime and other question content posted by users.
Chief executive Mark Zuckerberg said that the company is "working to make these videos easier to report so we can take the right action sooner - whether that's responding quickly when someone needs help or taking a post down".
Videos and posts that glorify violence are against Facebook's rules, but the company has been slammed for being slow in responding to such content, including videos of a murder in Cleveland and the killing of a baby in Thailand that was live-streamed.
The Thailand video was up for 24 hours before it was removed.
In most cases, content is reviewed and possibly removed only if users complain.
