YouTube has announced Safety Mode, giving parents more control over the content their family can view. (Thanks Robin!)
Safety Mode gives users the option to choose not to see mature content that they may find find offensive, even though it’s not against our Community Guidelines. When you opt in to Safety Mode mode, videos with mature content or that have been age restricted will not show up in video search, related videos, playlists, shows and movies. While no filter is 100% accurate, we use community flagging, hide objectionable comments and porn image detection to identify and hide inappropriate content. Safety Mode on YouTube does not remove content from the site but rather keeps it off the page for users who opt in.
