Add that to rule thread, or as separate threads. Maybe that'll (slightly) help things out.
Technically, it's rule 6: Think before you post.
On a side note, it's weird how everyone rebels against bannings that don't fall exactly into a rule's description word for word. It was mentioned already on a sidenote but it seems to be a running habit around here. I know you don't like it when some new-yet-old common sense based rule pops back up like shackles of oppression wrapped around an iron fist/hammer thing, smashing your soul and mind forcing you to think for an extra nanosecond before hitting that Post button otherwise incurring the wrath of the mods, or something, but come on.
This isn't rocket science, the expectations for behavior
everywhere in
any public setting are pretty simple and straightforward. Think, don't pull your pants down to piss on everyone, and you won't get into trouble. The internet may be a free hub for opinion and probably the highest level of freedom humanity has ever seen on a social level but it's still required that you atleast have a brain if you're planning on using it without everyone else with a brain kicking you out. As long as that condition is met you have nothing to worry about.
