"In an unprecedented attempt to maintain some form of creditability, the Wikipedia arbitration committee has unanimously voted to crack down on the Church of Scientology by banning all IP address assigned to the organization and its associates. The conclusion of this case marks the longest running dispute proceedings in the websites history, and the full ban goes into effect immediately. The ruling also represents the single largest ban handed down by the encyclopedia monolith, an accomplishment that I doubt the Church will be adding to their entry any time soon.
The accusations made by the Wikipedia board include several counts of failing to maintain impartiality, and using the service to promote its own personal agenda. Multiple editors from the same IP range were logged in and were accused of coordinating their efforts to force through changes. This type of behavior is clearly prohibited in the terms of service, and also prevents people from using the wiki to publish original research that cannot be properly supported.
During the dispute it was argued by the Church that those editing from Scientology IPs were acting without direction from the Church itself, however, a former member of the Scientology Office of Special Affairs suggests otherwise. "The guys I worked with posted every day all day," Tory Christman tells The Reg. "It was like a machine. I worked with someone who used five separate computers, five separate anonymous identities...to refute any facts from the internet about the Church of Scientology."
So did Wikipedia handle this properly, and more importantly, do you still trust their neutrality." more here
