NSFE 

(N)SFE stands for (Not) Safe For Exeos and describes if an anime/manga would be suitable for the discord user Exeos#6639 to watch or read.

They are very sensitive when it comes to character deaths in fiction, so they try to avoid any kind of series with deaths of likeable characters who you get to know in more or less detail.

A series is also NSFE if it has a sad ending. Sad and/or very emotional passages within the series are fine, as long as the ending is happy. A good example for this would be Kimi no Na wa.

Examples of NSFE -> Attack on Titan, Akame Ga Kill, Code Geass

Examples of SFE -> Fairy Tail, Love is War, Konosuba

NSFYE

An acronym that stands for "Not Safe For Your Ears".

As one example, you may use this acronym on YouTube when your video contains an audio (sound) component that some viewers may find distasteful, such as heavy metal music like Anthrax or Megadeth.

{in the YouTube description of a video I made and uploaded myself}:

*NSFYE* (Not Safe For Your Ears). A video of the Syma S107G R/C Coaxial Helicopter flying in my room, set to another Anthrax song.
Abort this video immediately if you find thrash metal music distasteful.

That music you hear is the song "Howling Furies" by Anthrax. This heli is not sound-sensitive; the audio may safely be ignored or even muted if it pisses you off.
