The chairman of Wikipedia’s U.K. fund-raising arm was banned from the service “for numerous violations of Wikipedia’s norms and policies,” after reports linked him to kinky bondage pornography and inappropriate editing. Ashley Van Haeften -- the head of the independent Wikimedia U.K. group -- was banned by an arbitration board on July 20, according to a story on The Daily Telegraph. The action was taken following a series of clashes over pornography on the popular online encyclopedia, and a series of edits to that material in violation of policy.
