First of all, SFW doesn't just mean safe for work, it means safe to browse in front of your parents, at school or just somewhere where having adult content on your screen would put you in an awkward position. It could even be at work while you're supposed to be working; if someone wants to do that and risk their job, it's their choice. The reason it's against the rules is that it would be far more inconvenient for the many people who browse the forum from a SFW-only place to have to stop browsing than it would be for the few people posting NSFW content to simply use spoiler tags. And though it's not as strictly enforced as I'd like it to be, it's not total anarchy here yet. I banned Supa from the forum temporarily after his latest series of unspoilered topless pictures but I think he's the only person to get banned. But, to go back to the main topic, I don't even think that two girls kissing is NSFW, otherwise I would have deleted it.
