Any post that considered "Not Safe For Work" (NSFW) will result in your account being banned. No warnings, no strikes, just a simple ban. Since some of you don't understand what is generally accepted as NSFW, I've taken this from FARK's website on NSFW.
* Nudity, partial nudity, or adult content: Naked people just aren't safe for work. Exposed breasts, nipples (including ones visible through material), weeners and beavers, and asses aren't allowable. It doesn't have to be complete nudity for it to be out of place at the office - a good example reference point is the Sports Illustrated Swimsuit Edition. It's not nudity, but most workplaces would frown on looking at it on company time - so anything you see in there shouldn't be posted here. A more general reference point would be to think about what you wouldn't want your boss to find in your browser cache. Dildos, vibrators, butt plugs, Ben-Wa balls, * sleeves, inflatable dolls, RealDolls(tm), and any other sex toys or devices used to penetrate or be penetrated are definitely not acceptable.
* Graphic content: Images that would make many people feel ill such as cadavers, autopsies, surgeries, vomiting, severed limbs, alarming deformities, roadkill, and bodily functions such as urine and *. Images in full, or in part of, or resembling Goatse man, Tubgirl, or anything equally as disgusting will be deleted and you account will be deleted. Images containing child pornography will be reported to your ISP and local/federal law enforcement agencies. The use of images depicting well-known tragedies such as 9/11 is not forbidden, but usually frowned upon. Images which depict people actually dying (falling to their death, engulfed in flame, being blown up) should not be used.
* If you're posting an image, and you're not quite sure whether it falls under the "safe" category or not, then link it with a very clear warning that it may not be safe. That way people can make their own decision whether they should chance it or not, and you'll be spared the ire of your fellow Belegarthians.
