Perhaps they are confusing it with the San Francisco Armory, a historic building the NIMBY neighbors blocked from being converted into housing so a porn company bought it instead and turned it into a production company instead.
Yes. I guess a few years of this was more than even the NIMBYs could take. It's now owned by some capital group seeking to build housing there, but new NIMBYs will come to the fore to block it, and the combo of declining SF real estate prices and rising interest rates may well make the project unviable, since a developer has to pay interest for a decade or more while stalling tactics delay approval.
Can't think why they'd add NSFW to that site, it's a plain text site primarily. I guess there may be something NSFW in the FTP archive somewhere, but I think that's probably an overactive filter.
As someone already mentioned nearby in the thread it could easily be something in the “purity test” content that has tripped an automatic naughty word filter.
It could even be the name of the site, depending on the location weapons and such might be considered NSFW (or for overly strict companies, not-relevant-for-work-we-dont-know-why-you-are-wanting-to-look-at-it-in-work-time!).
