Jonathan Dyles hoax with Whitehaven Coal raises the question of how far should citizens go in challenging what they see as corrupt or illegal behaviors particularly by business interests. The Yes men are 2 activists who have created a series of hoaxes to highlight particular issues.
In 2009 they created a Press Conferance as representatives of the American Chamber of Commerce and announced a reversal of the Chambers position on Climate Change. (interestingly enough 2 weeks after the hoax the Chamber actually did reverse its position...)
In 2004 the impersonated a spokesman from DOW chemicals to take full responsibility for the Biphol chemical disaster. They fooled the BBC into running that interview.
