You might want a re-cap on the forum rules....
Instantly Bannable Offenses
These can be one-time bannable offenses for which you will not get a warning.
Insults. Direct personal insult of another member, i.e., "You are an idiot." and all the variations. Why? Because this isn't grade school. People should be able to discuss or even dispute other's posts without insulting people. And the only purpose of a post like this is to incite other people. You may dispute somebody's opinion, but not attack/flame the person who stated it. There are a lot of other non-direct-personal insults that won't necessary get you banned instantly, but depending on the context/nature may lead to post editing, post deletion, warnings, or time-outs. They include telling people to shut up, or being extremely or repeatedly rude or sarcastic.
But you probably read this already....
Oh and here's another:
Things Not to Do
These are usually not instantly bannable - but will likely get you edited and/or warned.
Useless posts. Do not bother making posts with only one or two words (e.g., LOL) or a smilie, or post simply to have the first reply in a thread. Such posts waste everyone's time and will be deleted. Posts saying "I agree", "me too", or the equivalent are also routinely removed.
Have a good day.
