We have recently been hit by upward of 100 spam comments a day. Although we have managed to keep them from actually appearing on the blog, it has meant a huge amount of overhead for me to deal with.

In order to eliminate the problem, I have been forced to add an annoying hoop to jump through before you can place comments. When you go to post a comment, you will now have to type the number that appears on top of the image.

Please let me know if there are problems with this.
