This is an old topic from Reddit, sorry about that, but I think the community would benefit from separating porn and other types of nsfw by adding the nsfl tag.
I've seen several posts lately of people complaining about porn showing up in their feeds and the posters say that they don't want to block all nsfw posts because they follow other things, like news from the war in Ukraine, that gets tagged nsfw because of graphic imagery. I think they have a reasonable complaint and that the best solution is to separate the two types of content such that porn is tagged as nsfw (not safe for work) and graphic images/gore/non-sexual nudity ect are tagged nsfl (not safe for life). It may not be entirely fair to label non-sexual nudity, medical posts, and I'm sure many other categories that aren't jumping to mind right now as not safe for life but nsfl is an already established and generally recognized tag and I don't think there's any real advantage to having more than two tags.
But there are things that would constitute NSFW that aren't porn and also not NSFL. I think a way to designate porn makes the most sense so you know whether you're clicking on a video of a bad car wreck or a video of a woman being raw dogged from behind.
I addressed that at the end of my post for how I was thinking about it. I was using nsfl as a catchall for non porn nsfw because I didn't want to add lots of new tags, just have a porn and a not porn one. If porn moves to a new tag and everything else stays nsfw I wouldn't use nsfl, I'd go with akai's suggestion and just make the new tag be "porn" or something similar.
How this is confusing people or purposely being obstinate is beyond me lol.
There REALLY should be two separate tags for content like you've said.
NSFW = Porn.
NSFL = Gore.
That's it lol.
