Wikipedia has banned the Church of Scientology and its members from editing its site after discovering that members of the church were editing articles in order to give the church favorable coverage.
The move is being hailed as "an unprecedented effort to crack down on self-serving edits," and it is the first instance in which Wikipedia has banned a group as large as the Church of Scientology.
