By posting on the game chat, you agree to abide by the rules. If you choose not to read them or ignore them totally, that is NOT the resposibility of the staff. Ignorance of the rules or ignorance of your violation of them is no excuse.
That being said, most of the staff, most of the time make a good effort to help people understand what`s going on. Verbal warning are usually given with a brief explanation of the violation they are being warned about. MOst of us staff try to be fair. But repeated unheeded warnings and repeat offenders are well aware of what they are doing and need no explanation.
