NSFA 

Not Safe For Anyone. Not only are all NSFA things considered NSFW, but you would look at these things at home, with the curtains closed, and no one watching you. Borderline disgusting to most reasonable people. Known to corrupt small children.

Bob: hey, want to see my image folder on the server?
Steve: k, sure
Steve: *checks and sees it's full of guro*
Steve: good god, nsfa tag, maybe!?

NSFA - Not Safe For Australia

Due to stories spread in January 2010 about Australia banning small breasted women in pornography due to "promotion of paedophilia" a new meme was created to indicate if a photo/video is considered illegal in Australia.

Damn, I bet those titties are NSFA!

NSFS 

"Not Safe For Straights", a tag mostly used on twitter by gay people, used during and before Pride Month, users are not allowed to post any straight content under their tweets, or the kpop stans will go after you.

It started as a mockery of "Not Safe For Ramadan", but is now widely used across twitter and is now yearly occurrences.

Yo not cool bro my name says right there (NSFS), why are you replying with men fucking pussies on my tweets?

NSFTS 

Acronym meaning "Not Safe For This Site", which means that the content that it is directed towards is not appropriate for posting on a website or forum within due to content regulations.

(In the case of a forum, say a children's literature forum) Dude, that porn link is NSFTS.
