If this gets implemented, we should name it something other than NFE because it may confuse users. For example, a user might want to keep their project a bit more private, but are hesitant to make it NFE because they think they might get in trouble because their project is actually appropriate and shouldn't be NFE by the rules' standards. Does that make sense?

Users might try to make inappropriate projects and mark them as NFE because they think that NFE is like a 13+ rating or something.

Based on what I can tell, the NFE rating (aside from animated thumbnails) means that a small amount of users could get triggered by the project (such as users with epilepsy, users who get triggered by seeing small traces of blood, users who get reminded of racial violence when they see hangman projects, users that get scared when they see an appropriate project with FNAF characters that gave them nightmares, etc.), but it is still allowed.
