Looking for spam blocking code 1

[algraff]

I've been getting flooded by spam-bots in a guestbook form on the order of hundreds of entries per day. I've been looking for some code to require submitters to type in a random set of characters to verify they're not a bot but haven't found anything. Could someone point me to some sample code or a tutorial on the subject? Thanks.

Have a search for CAPTCHA. There are many server-side examples already built that you can just slot into your site.

I stumbled across this PHP implementation of a CAPTCHA which you may find useful:

Since I did't want to bother using captchas, I wrote my own (simpler) method :

Why is your method simpler? Do you mean simpler as in easier to implement or simpler in terms of security/features? What happens if the OP isn't using PHP?
