Some websites give users the option to designate their content as NSFW in order to warn others of its inappropriate nature. Links marked NSFL may contain fetish pornography, gore or murder.
The similar expression not safe for life ( NSFL) is also used, referring to content which is so nauseating or disturbing that it might be emotionally scarring to view. Conversely, safe for work ( SFW) is used for links that do not contain such material, but where the title might otherwise lead people to think that content is NSFW. NSFW has particular relevance for people trying to make personal use of the Internet at workplaces or schools which have policies prohibiting access to sexual and graphic subject matter. Environments that may be problematic include workplaces, schools, and family settings.
The marked content may contain nudity, pornography, political incorrectness, profanity, slurs, violence or other potentially disturbing subject matter. Not safe for work ( NSFW) is Internet slang or shorthand used to mark links to content, videos or website pages the viewer may not wish to be seen looking at in a public, formal or controlled environment. For other uses, see NSFW (disambiguation).
