This site is running the spam filer Spam Karma 2.0. It has worked beautifully since the moment I set it up. I bring this up because I was just checking to see how it was working and I noticed something funny. Spam Karma is automatic, there is virtually nothing for me to do. It approves or rejects comments based on a series of filters, and will even blacklist IP addresses or domains which send it too much junk. There on my list of blacklisted domains is Microsoft.com. If I’d thought of it I might have blacklisted it myself just to amuse myself, but Spam Karma got it for me. You have to love it.
