"I only want two kinds of email: those from people I know, and those from people who have taken the time to find out what I'm interested in and composed a note meant to appeal to that (I love those emails; indeed, that's why my email address is public). Everything else gets banned on first abuse." Full post here.
Chris then publishes a list of about 300 banned email addresses, a real who's who of public relations practitioners. Comments to the post are entertaining, mostly supportive of the initiative. There are some PR guys whining in the lot (the entertaining part).
Personally, I hope that this will be a wake-up call for lazy PR execs who spam bloggers with press releases or who infringe editors/journalists' personal space. I do receive about 2 emails a week, nothing like what Chris Anderson must be dealing with. I rarely follow-up as they often consists of a copied and pasted press release about some topics I couldn't care less about (some company won an award in Oregon...). Sometimes there is a short note offering me an interview with some executives I never heard of (to talk about awards won in Oregon...).
When I was working with Hill & Knowlton, we went to great length to build relationships with bloggers. It takes a lot of time and efforts but the end result is that you don't end up in a banned list like Chris Anderson's, for all to see and to spam you in return.
