America’s second largest provider of pet insurance, Seattle-based Trupanion, confirmed earlier this week that the company is now blocking The Canine Review’s domain name. Many academic and company servers filter pornographic content and, of course, there are other historic examples such as Instant Messenger, the messaging application, and online games such as Snood; all were regularly blocked by company and academic servers. But no other U.S.-based company we’re aware of has ever blocked a news organization.
