The rule is fine, the problem comes when you get cuntbag admins. The rule is there so that if everyone goes, "this map is worse than the Holocaust run by blacks," then the admin does everyone a favour instead of the RTV routlette.
The problem comes when you get admins who forget that the only reason they're there is for the enjoyment of the players, so you get people like Meltdown who are frigid cunts who only do things for their own amusement and sholdnt even have admin but rather cancer.
In the end; the rules are fine, look at those who are inforcing them for the reasons why there are issues.
