Thank you so much for this feature.

We've been having a problem with a spammer on our guestbook and since there was no IP ban capability, we were at our wits end. Even though his IP is banned from our website, he evidentially had the guestbook bookmarked and accesses it directly.

This helps nicely because now his messages won't see the light of day to begin with.

Thank you so much for your hard work on this!
