People seem to think that spam bots are fairly stupid, but I've played the cat and mouse game with them and they've been surprisingly smart. I added an encoded cookie to the main page of the site which you needed to post but spam bots had no little trouble with that. On another site, I used simple math captcha -- but it was too simple and didn't even last a day. It seems to me that simple replacements, such as the above, would be the first thing most bots would handle.
