I have managed to spam-proof my guestbook with a simple script at the bottom generating a small string and asking the user to input it to create an entry. This will fool all but the most intelligently-designed robots and has reduced my guestbook spam to a minimum. It works by hashing a combination of the time period, page requested and user ip address to produce a unique key that lasts a few minutes. Hopefully my ranking on search engines will now improve with the removal of all the spam entries — Google has put me on page four and I’m hoping that was simply because of the spam messages.
