We send them greeting cards with money, gift cards, and other assorted goods. By acknowledging their inferior status with a series of humble presents, they will not only understand their place, but they will also graciously submit to our iron fist of power without putting up a fight, as they will think that we are generous and affable.
Also, the greeting cards are actually letter bombs.
They are wrong because they support an evil man. System was doing a fine job of running the site, yet he constantly received insults by people calling him a bot. I'm sure most of us would be offended if people constantly called us a bot for years. Eventually he got fed up with it and left, whereupon he was replaced by Chester. Now System has returned to claim the position that is rightfully his, and no one can stop him!
We could give some of our users a fake ban, then make them cry about it aon the IIRC and then fake a PM from Chester to the "banned" person in which he would say how fucked the person is now. I think that all the Chester side guys see him as the nice person who would never ban someone and fuck with him then. So that kinda could work.
