Cyberpresse is now requiring all comments on all blogs to be approved before they are published, according to Richard Therrien and Marie-Claude Lortie, similar to what currently happens on the high-traffic Patrick Lagacé blog. The reason is simple: Cyberpresse considers itself responsible for all content on its website, no matter their origin.
It’s not entirely their decision. The Conseil de presse has published several decisions regarding blogs and recommends that all blogs be moderated. (Unfortunately I have trouble finding the links to the exact decisions on your site… I’m sure you already have them on your blog!)
