The problem is, the spammer is using multiple IP Address. His IP Address
changes every 6 - 8 entries. I have so far recorded 5 different IP Addresses
of the spammer. Although I can create a Database and keep adding his IP
Address to the database, and run a check from the Guestbook script to scan
against Blocked Addresses, It's not the most efficient method in the world.
What other logic can I apply to automatically block the spammer? Or at least
have a more efficient method of blocking the Spammer and his IP's?

You could always block a range of IP addresses, but you may cut out
a legitimate user.
I'm missing the beginning of this thread so maybe it's be mentioned
before but is an image
CAPTCHA not an option? (and yes I know the accesibility arguments
against using CAPTCHA,
and the fact that crap CAPCHTA can be broken by image recognition
tools - but my pragmatic
feeling is that it's often better than a bucket load of SPAM.)
<disclaimer>
Not that I promote CAPCHTA, but there are simple solutions that will
slow down some spam while allowing some with vision problems to pass,
such as --
http://www.xn--ovg.com/captcha
-- namely, the graphic selection demo.
Granted it's not the best, it doesn't solve everything, and I never
said it did (at least no one can prove it) -- so don't whack me for
it -- it's just a suggestion.
