Nobody actually posted dirty pictures or anything in the thread itself. The thread itself is SFW, because you can click on view it and it won't embarrass you in the office. The word "goatse" itself is SFW. However, I recommend against googling it, because you'll likely come up with images that are NSFW.

If there are any offlinks to NSFW content, those should be labeled. I'm content to rely on individual monks for that labeling, falling back to editors when individuals fail.
