NEW YORK — Facebook plans to hire 3,000 more people to review videos and other posts after getting criticized for not responding quickly enough to murders shown on its service.

The hires over the next year will be on top of the 4,500 people Facebook already has to identify crime and other questionable content for removal. CEO Mark Zuckerberg wrote Wednesday 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 Facebook has been criticized 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.
