Video-sharing website YouTube has removed hundreds of pornographic videos which were uploaded in what is believed to be a planned attack.
One user believed to have uploaded some of the pornographic material videos is Flonty, whose profile states that he is 21 and from Germany.
He told the BBC: “I did it because YouTube keeps deleting music. It was part of a 4Chan raid.”
4Chan is a bulletin board focusing on Japanese manga and anime but some of its more extreme sections have been described on online messageboards as “sick” and “horrifying stuff”.
