Tom Cruise, put down your laptop. Wikipedia’s arbitration committee has voted to block contributions from members of the Church of Scientology after users complained they were editing the website to push propaganda. "Newcomers are treated rudely. Bad faith assumptions, personal attacks, edit wars, soapboxing, and other disruptions are common occurrences," the committee said. Anyone who logs in with an IP address traceable to the Church will be blocked from editing articles about Scientology. Wikipedia, the most-used online reference site, strives for impartiality in its entries but has been criticized for its occasionally unreliable content.
