Weird. If you ever see the error again, please write it down or take a screen shot and share it with us.
I finally had a chance to read the entire page of proposed changes, and unless I've grossly misunderstood something, we're not banned from discussing and documenting an NSFW work -- we're just banned from hosting the work itself. Of course, the question becomes, will it stop there? Or will it eventually creep -- or leap -- into TVT territory, where we're not even allowed to acknowledge that NSFW works exist? That's something I'm going to be discussing with my fellow mods.
