I read a few other anti-spam blogs.  There really are some good ones out there so I thought I'd share my top three.

1. Al Iverson's Spam Resource - This is perhaps my favourite blog because the author, Al Iverson, so frequently has interesting information on there such as the accuracy of a number of blacklists as well as updating his readers on the status of his ham/spam tracking project.  His dnsbl.com is also worth checking out.
   
   
2. The Spam Diaries - This is a page run by Ed Falk and the content he has is very informational.  I really like his high-level overview of that happenings of the Spam World (Spamatopia) but also of stuff like the SEC cracking down on pump-and-dumped stocks, and legal crackdowns on spammers.  For somebody like me who fights spam I definitely enjoy the insight that I would otherwise miss.
   
   
3. The Internet Patrol - This is another site that I read frequently.  It frequently has articles to relevant issues in the world of spam-fighting.  I look forward to getting articles in my RSS feed from The Internet Patrol.

These are not the only spam blogs that I read but they are definitely among my favorites.  Keep up the good work, fellow anti-spam bloggers.
