Live video has become increasingly controversial as social media sites have encouraged use of the tool but have struggled to monitor it.

The most prominent example was when four Chicago residents kidnapped and tortured a mentally challenged man in the beginning of January, broadcasting the whole thing on Facebook Live. It was eventually taken down by Facebook, but not before it had been shared and embedded by others.

Another incident with live video occurred on Dec. 30, this time originating on another site with livestreaming capabilities called Live.me. That was the day Katelyn Nicole Davis, a 12-year-old in Georgia, decided to kill herself in a 40-minute live video after saying she had been physically and sexually assaulted by a family member, according to BuzzFeed. A Facebook page started in her memory details signs she may have suffered from depression.
