Since I couldn't find a captcha modification and I do not want my blog to turn into a link directory for spam sites, I hacked in a captcha system into Greymatter.
Attached is a ZIP file that contains a patch for "gm-comments.cgi" and a new file called "gm-captcha.cgi". This mod depends on Authen::Captcha which you can install via CPAN. Template changes are explained in "template-changes.txt"
You will need to know how to use .patch files to install this. Also, both files will need to have "$output_dir" modified in order for the script to work.
Unfortunately there is no "readme.txt" and I am not providing support for it. I don't have the time.

Thank you very much for this mod. This is great. I was planning to add captcha to my comment moedration queue mod which I will hopefuilly get back to evry soon. I have been writing a number of presentations and speaking at conferences for my day job over the last 6 weeks or so and had little spare time for gm -
I have downloaded your mod and will have a detailed look through and will install it against 1.3.1 as well if i have time as i think a lot of people are likely to be still on 1.3.1
Not sure how to patch a windows file, but Greymatter does have a similar functionality. Under the configs enable "Commenter Verification". And if you are worried about spam, try both "Verify Site Comment/Karma Vote Posted From" and "Comment Throttling" options.
After turning on the "Verify Site" option, I haven't had any spam.
