It appears that you've pinned yourself, Surburb. This topic was already prone to backfire, there was no need to strike back, yet you still found it necessary to throw yourselves into humiliation by subjecting yourselves to such a wide spread of perspectives? That isn't a smart thing to do, and I of all people would know. Your best bet is to stop subjecting yourselves to such drama, and eventually it will surpass without any affect to you, your administrators, or your server.
This situation deserves some observation, however, so please place yourself into the shoes of Jasa, who has continually worked his ass off for your server, only to have you issue to him a ban like he was nothing more than a measly guest who had been causing trouble.
Not to mention, you went on a wide killing spree yourself, and other players who had done the same weren't punished as Jasa had been. There's also lack of civil coding to base your bans on, because I have yet to see a rule book with civil laws that include some of the following laws, such as excessive killing, ghost killing, and chat spamming.
It would be of best interest to remove Jasa's ban, and in turn recognize him for his effort towards your server, totally disregarding the situation he had put you through.
Please remember that I've had the same situation with you, yet I still managed to forgive you. After all, you did give me a swell idea for an overpass, as Jasa gave you a swell city to start your server off with.
