A Japanese civil servant has been demoted after he viewed pornographic websites more than 780,000 times during office hours over a nine-month period. The man, an employee of the Kinokawa government in western Japan, visited porn sites from June last year to February 2008, Kinokawa official Tomiko Waki said. Despite his frequent porn viewing, none of his colleagues noticed his activities. Waki said: "Each desk is set apart from each other." The man's superiors discovered his extensive porn site visits after his computer became infected with a virus, prompting officials to examine his web browser's history.
