What is nsfl?

NSFL stands for "Not Safe For Life." It is an internet slang term and content warning used to indicate that a link, image, video, or other content contains disturbing or graphic material that may be extremely upsetting, offensive, or harmful to view. The content could include graphic depictions of violence, gore, sexual abuse, or other forms of extreme content.

Essentially, it's a stronger warning than NSFW (Not Safe For Work). While NSFW content is usually just inappropriate for a work environment, NSFL content is generally considered deeply disturbing and something that people should avoid if they are sensitive to such material. The warning is intended to allow viewers to make an informed decision about whether or not they wish to view the content. Common content flagged as NSFL might include graphic medical procedures, depictions of extreme animal cruelty, or violent accidents. Because of the disturbing nature, many online platforms have rules against posting NSFL content, or require it to be heavily censored and clearly labeled.
