At the beginning of last week, Chris Anderson, author of The Long Tail and the Editor-in-Chief of Wired, announced that he was permanently blocking the email addresses of PR people who had sent him inappropriate email and published a list of those addresses. The post garnered a lot of attention, and a couple of days later (Nov. 1) he posted a followup: PR Blockage: The Aftermath. Definitely worth a read if you have any involvement with media relations.
