Lawyers for Richard Warman, Canada's leading online hate fighter, have filed an application with the CRTC requesting that it issue an order enabling carrier ISPs to block two foreign hate sites that have issued death threats against Mr. Warman. One of the sites – a blog hosted on blogspot – has since been removed. Assuming it proceeds, the case raises some interesting questions: the two sites are vile, but is the CRTC the right place for this to happen? If the CRTC does issue such an order, will it face a regular stream of similar requests? Can the sites be blocked without also blocking dozens or hundreds of additional sites hosted at the same IP address? More on a case worth watching at Mark Goldberg's blog.
