Social Networking giant Facebook has started putting warning labels on graphic videos that members upload and share with friends.

The company says it will also prevent shocking or upsetting video clips from popping into News Feeds of members whose profiles say they are younger than 18 years old since

Facebook allows children as young as 13 to join.

“When people share things on Facebook, we expect they will share responsibly, including who will see that content,” a Facebook spokesman said.

In cases where people report graphic content to us that should include warnings, or is not appropriate for people under the age of 18, we may add a warning for adults and prevent young people from viewing the content, the  spokesman added.

In November Facebook introduced a feature that causes videos in News Feeds to automatically start playing.  Users must now click on warning labels for those videos to play.
