Is your guestbook a script you wrote yourself or something pre-made?

There are two solutions that people use to reduce spamming in these instances.

1. Flood control - where a given IP address is not allowed to make a second post until a cretain length of time has passed (I use 15 minutes as the same person is unlikely to keep trying for that long and after that the IP address may have been allocated to someone else).

2. By displaying a generated image on the page that contains a code and requiring the code to be correctly entered into a field before the post will be accepted. This blocks the spambots that can't read the text in the image.

BINGO! You can also refuse form/url id submissions from any other domains other than the parent domain.
