Steemit NSFW and Users blogging content

It obvious that most users of Steemit don't get their save oriented with Steemit terms and conditions before beginning posting. In these post, my aim is to draw as many users attention to the steemit acronym- NSFW.
NSFW means Not Safe For Work: it is used to prevent content that may not be appropriate or desirable for some of readers or Steemit users depending on their current location, age, background or personal views.

How does NSFW work?
Depending on the users settings. Whenever a content is posted and it contain pornography the content will be hide or a link shown.

To toggle through the NSFW options it is necessary to go through setting- then at the end of the setting page before update, the NSFW is found. Below is how it is shown.
