Yesterday I started getting hammered by comment spam here. To combat it, I’ve instituted a random text generator. When you comment from now on, you simply copy the chracters you see in the image into the box next to it. Automated spambots can’t do this, and thus can’t post comments.
Note that if you mis-type the code, your comment will be lost.
A bit of a pain, yes. I hope you’ll bear with me.
