Verbose, as much as you'd love a series of site rules that contain so much detail you'll drown in it, it is simply not possible.
- X and Y both aren't allowed.
- Y is however allowed when hidden below a nsfw tag.
- X is only allowed when it features a specific type of content.
- That of course means that X has to stay relevant to the topic.
- Y is also only allowed between the 25th of January and the 3rd of June.
- That of course means as well that the black bar on X should be at least 2 cm wide.
- Unless you add Z to the mix, then the nsfw tag on Y isn't needed.
- But not in combination with Q, that's overboard.
- And then I'm not even mentioning T, oh dear lord.
See how confusion something like that quickly gets?
I'll stick with the discretion of moderator rule. By times, we have put up various notes and warning around the forum telling people that what they've been posting now is going overboard. Besides, it's not like we're banning on sight. We often send people warnings that something is going overboard. If they disagree with us removing it, they can always tell us their reasons and we'll try to explain it. If he can tell we were acting incorrectly, we can take that in mind next time. Mods aren't perfect, they're still human. We make mistakes as well, remember that. So don't blame us for being sucky mods when it goes wrong one time.
Just remember to stick to the topic and add a warning note when in doubt. No really, nsfw tags make a huge difference with questionable content. Especially if the topic itself contains a "NSFW" tag. Because when it's tagged NSFW, you offer people the option to not look at it. If they then still decide to look at it, that's their fault and they are to blame if they get scarred. If you're really unsure, you can always jump in the IRC and ask for opinions there before posting it. We allow pretty much everything in the IRC, so we can give you a heads up if it's save to post. When something is so hardcore that even a "NSFW" tag won't do anymore, you should be able to tell so yourself as well.
But let's continue there, how about the discretion of users. Because currently it only seems that moderators are to blame. That seems like a pretty lame excuse to me if an user breaks the rules, just blame the mod that jumped in and did his job. The moderators might jump in when the content has been posted, but it was the choice of that specific user to post it. When he posted it, he knew exactly what he was going to post. We can take for granted he read the topic of the thread, whether that topic contained a warning, whether his post is relevant to the topic, and whether or not his own post contains a warning. If he didn't, that's his fault and only that user should be to blame. By that, all consequenses coming with that post are also his. If he can't read the site rules and doesn't have a decent brain in following them or put his own opinion on his post, that's his fault and so are the consequenses.
