For the uninitiated, generally NSFW is for sexual contents and NSFL is for gory contents. People may want to see one but not see the other at any time for any reason. I have seen this feature requested over the years in Reddit but it never happens. Maybe now some instance can finally implement it?
What is NSFL?
I've never seen or heard of it before.
NSFW is not a Reddit thing. It was around and already popular years before Reddit came along.
I agree that NSFW should be more granular but let's keep the acronym because everyone already knows what it means and I see no reason to move away from it.
NSFL isn't as common as NSFW but it's still an established acronym.
Apparently NSFL is barely used in comparison to NSFW based on Google Trends; no wonder I've never heard of it before.

Not Safe For Life. Usually it is something horrific that many people never want to see… Unlike boobies.
