Some idiot spammed this blog, adding comments to every single article. I have had to change things a bit so that I approve comments. It won't change anything for you folks, except that you'll have to wait a bit for me to read your comments before they appear on the site. I hate to do that, but it took quite a while to clean up the blog.
I think there is a way to block IPs, but I couldn't find it. Still, I can't block a spammer that hasn't spammed me yet. There are plenty more out there besides the asshole who was just here.
