Well there is also this use, I do not want to see ACTUAL porn. The only fans, “college students have fun!” Type shit. I’d LOVE there to be an option to block that. As far as literal “nsfw” I don’t care about that. I don’t care about potentially sexy posts or art or whatever. Let the author decide if it is porn and tag it as such and not enforce any sort of rules or regulations on it unless a community or instance decides to.
Oh but this isn’t an either or, I agree NSFL is a very helpful thing we should also have. I don’t wanna see gore and human or animal suffering.
