For example this Arbitration Committee spoken of - in mid-2005 Wales appoints an editor so biased against Palestinians, Arabs and Muslims that Wikipedia Review has a whole forum on this editor - JayJG ( http://wikipediareview.com/index.php?showforum=46 ). People find him incredibly biased and the vote of all Wikipedia in early 2006 for ArbCom members kicks him out. But Wales is not happy with this and decides to stuff ArbCom, like FDR threatened to stuff the Supreme Court. So Wales creates a new ArbCom seat. Does he appoint the Wikipedia-wide next highest voted neutral editor to ArbCom? No, he reappoints this Arab and Muslim hating editor JayJG.
You can find many examples of this sort of thing. With Wikipedia, the rot starts at the top. One day, a rival wiki encyclopedia will come into play and trounce Wikipedia (or at least be an alternative to it).
