Comment Spam Blocker

Nov 16, 2004

I have installed a new spam blocker in my discussion area (the place you reach when you hit [Reflect]). Actually, I had several running, one which actually blocked all comments - a little less than useful. If you had a problem posting a comment recently, this should be fixed now. But I still have my main spam filter, a wonderful array of misdirects and hidden keywords designed to fool automated systems and yet let real people post comments anonymously. I'll email the code to anyone I know who asks and promises to keep it reasonably well hidden. It's in Perl only, but of someone wants to code a PHP bit it should work equally well for wikis (assuming it works reasonably well - I'm still testing, but so far it has worked beautifully).
