Back in the day, on other forums than this one, there were tags to differentiate between porn (nsfw) and gore (nsfl). This was nice for people browsing new that had no problem seeing tits, but wanted to avoid degloved hands.
Throughout the years, the NSFL tag went out of use. What happened?
I think there’s a huge range of stuff that’s legal but that many people might want to filter out because it’s gross or disgusting.
The tag “NSFL” may have been created for the most egregious pictures (that might be illegal in some cases), but it was generally applied to a much wider range of stuff in practice.
