[snip] 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?

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. </disclaimer> tedd -- -------------------------------------------------------------------------------- http://sperling.com
