8.2. It was added in old rules under different format I just changed it and made it simply as cheating is not allowed. Otherwise explaining more is not necessary as swim mean swim and following the command exactly as said is to follow the command as exactly said. Simple.
Actually I disagree, reading all the time repetitive words make rules boring and not enjoyable. I made them in the most sufficient way so people who are new could read them quickly through and memorise. Also it is not hard to scroll back up and see whether it was T or CT rule.
Explaining is good, but my personal experience shows that people don't read the rules and if they did they didn't understand them anyway. I learned rules by playing the game, so this is an easy way to quickly look through not read like a book. Also by having large texts there's a fat chance that every rule will collide with each other not to mention that because of you people who also took hands in the original rules adding and configuring them after made even more mess, but I think it was messy before.
Haha and no, I was thinking to put that after every rule - you risk of being kicked transfered etc.. Again people don't want to read same thing over and over again, this is the reason I added :
By breaking these rules you risk being transferred back to T team or kicked without a chance to be CT again for the following map.
About the vent rule, actually even in the old rules it is not stated and no one bothered really to look at this rule from different situations, that's why this rule got so many gaps. Usually CT don't go in the vent after he have already been there (after 30sec warn) so this is discussable only in admin meeting.
