Guess Tom Cruise's been editing it too much 
The collaborative online encyclopedia Wikipedia has banned the Church of Scientology from editing the site. The Register reports Wikipedia’s Arbitration Committee, or ArbCom, voted 10 to 0 in favor of the ban, which takes effect immediately.
Wikipedia’s innovative free-encyclopedia draws upon the knowledge of millions of users to create and edit articles on every conceivable topic. Edits appear immediately and do not undergo any formal peer-review process.
Wikipedia officially prohibits use of the encyclopedia to advance personal agendas – such as advocacy or propaganda and philosophical, ideological or religious dispute – but the open format makes enforcing such policies difficult.
According to Wikipedia administrators speaking to The Register:
Multiple editors have been “openly editing [Scientology-related articles] from Church of Scientology equipment and apparently coordinating their activities.”
Entry's still on Wiki but has a lock symbol on the top of the page.
