But the term "NSFW" isn't limited to just sexual content.
[...]
It's true that sometimes the term NSFW is used in such a generic way, or interpreted in such a generic way, that it can create a broader idea of what it really is.
And that’s a big problem: The term is vague, arbitrary, and capricious—totally subjective. If, hypothetically, the forum rules were a public law (instead of a private entity’s policy on private property), then in its U.S. constitutional jurisdiction, Rules 10 and 31 against “NSFW” would be declared “void for vagueness” in an ACLU free speech lawsuit.
Indeed,
any First Amendment lawyer would tear “NSFW” to shreds with a facial challenge as “void for vagueness”, if the term were used in a censorship law—or even any first-year law student who aspired to constitutional law. This is First Amendment 101.
Moreover, the vagueness of the term causes
chilling effects on speech. I lack psychic powers to read the moderators’ minds. When I need to guess what meaning moderators will ascribe to “NSFW”, I must self-censor within smaller boundaries than what’s actually allowed—or else take the risk of potentially violating the rule, as nully did with the vulva painting he truly had no idea would be prohibited.
It [“NSFW”] may include:
Graphic violence - Serious injuries, mutilations, corpses, excessive blood
Disturbing content - Serious accidents, shocking images, extreme suffering
I believe that’s all what the forum’s Rule 31 calls “NSFL”: “Not Safe For Life”. Well, I guess. Who the fuck knows? The terms are meaningless—which is
a part of my point.
Explicit language - Serious insults, sexual or extremely offensive language
Why is “sexual” grouped together with “serious insults” and “extremely offensive”? I don’t share these moral value-judgments, and I don’t accept them being imposed on me. Please question your own premises, and examine the sex negativity embedded in your assumptions.
Other sensitive content - Certain content related to drugs or dangerous behavior
Censorship rules have such a tendency to expand in their ambit,
especially when the rule is defined so vaguely.
It's true that sometimes the term NSFW is used in such a generic way, or interpreted in such a generic way, that it can create a broader idea of what it really is.
So, it’s
designed to be vague and over-broad.
The term needs to die. If we need labels for censorship purposes, then the labels should at least be precise and descriptive.
Naturally, there are workplaces where one regularly deals with content that is commonly classified as NSFW. But that doesn't make the term inappropriate or meaningless.
It is prejudicial against those workplaces, as I stated in OP. The language is a values-laden dysphemism which invalidates “not-safe-for-work” workplaces.
I think the problem is focusing this term solely on pornography.
For example, in a pornographic film production studio, this type of content is perfectly suited to the professional activity. However, graphic images of crime scenes may not be.
That’s an intriguing hypothetical, but I doubt that anyone uses the term this way in practice.
In a police station, the situation may be reversed. Images of crime scenes may be part of the daily work, while pornographic content would, in principle, be inappropriate.
That's precisely the point: the term NSFW relates to the context and appropriateness of the content, not just to whether it's sexual or offensive.
Police agencies deal with a ton of sexual content, to police it. What a job, the sex police!
Inter alia, they seek illegal porn; in this forum’s U.S. jurisdiction, that’s (a) child pornography and (b) obscenity, as (vaguely!) defined by law. Along the way, they need to look at lots of legal porn, too. The DOJ/FBI have various
departments devoted to this [⚠︎ link to U.S. Federal police agency]. What’s “NSFW” at their job?
NSFW is a universally recognized way to warm about opening a link in public. It applies to all public events and not just your place of employment. I appreciate being able to type NSFW instead of wasting space using a more precise warning.
It’s
not “universally recognized”. It’s universally vague and subjective; everybody has a different definition. Words used in rules need to have precise meanings.
appropriateness
See? Joker just summarized my entire statement in one word.
To some people, an animated cartoon of a man licking his own breast and the phrase, “licking my boob” are
inappropriate. Oh, how “inappropriate”!
Licking my boob since 1970* Meretrix swoons from the inappropriateness, which is definitely Not Safe For Wife.
In your opinion,
does it violate “appropriateness” for a woman to lick her bare breast in public? Do you think that a female-presenting version of your cartoon avatar would violate Rule 31, which prohibits “NSFW” avatars? If so, the rule is structural gender discrimination, and it enshrines male privilege. You can cartoonishly lick your boob all you want.
If I have a cartoonist illustrate me licking mine, do you suggest that I could use that as a forum avatar?If I try it, and I get in trouble, will you stand up for me, honey?

The word “inappropriate” is another pet peeve of mine. It’s a weasel-word, as meaningless as it is moralistic. So is “decency”, as in the “Communications Decency Act”; if the CDA hadn’t been struck down as unconstitutional in the U.S. in 1997, then this forum could never have existed.
