Well lets set this straight. Admins see sides of players that normal players do not. Some of the people you have mentioned i KNOW have tried to get other players banned, have asked ME and other admins to ban players for them, and have tried to break rules in front of Admins because they think they "can get away with it" (because they are friends).
There are some of the reason's why some people on that list are unsuitable. Others i personally couldnt talk about (Duke for one) as i have not seen them play for very long (or they have had a name change, which is starting to really annoy me, i get to know a player and then BOOM name change and I do not know about it!).
Although cheater/rule breakers are frustrating if management/admins see a player we believe would enhance the LW team then we will have a discussion on it (in private) and decide so its fair and peer selected. Although the suggestions are good, as i say, admins see sides of players that others do not, so we get a sense if a player would abuse the position/power, break rules, etc.
