Here are the flaws with your idea, and I mean this with the utmost respect Ownz so don't take it as a personal shot.
Zero, he is a busy man. Not only does he have to handle the vast majority of everything IBIS related, but he also has a social life, and a complete life outside of IBIS. I feel we put enough burden on him as it is, and people like kavinsky don't understand how busy he truly must be.
And in all honesty, I wouldn't want him deciding who should get banned anyways. I mean come on. Look at the Hallwagner scrape. Zero had faith in that kid and gave him how many chances, when it was clear as fucking day that Hallwagner failed at being an admin, and as a player. No offence Hall. He gave him how many chances? WAY TO MANY and I'm sure you'd agree with me on that one...
Needless to say, Unless the structure of the authority system of IBIS were to change, than your idea wouldn't work. A few, very select, number of IBIS community members are rational enough and intelligent enough to make these sorts of decisions. If Zero implemented your idea, and allowed those very few and far between individuals to make the judgment calls, than it would be an astounding success in my mind.
And never forget Owns, I <3 U!!!!
