towards a better comments spam filter
Oh and post comments here to make sure I haven't broken it for everyone :-)

Oh, and one silver lining to this: having to go over old "real" comments to weed out the spam made me realize that I really do appreciate how much the comments feature has addded to this place...

Ever consider Bayesian filtering for comments?

Well, that's one of the downsides of homebrew software, either having to roll your own or integrate w/ someone else.

Comments spam seems much less sophisticated than its email brethren, so at least for now that kind of filter might work really well. Still, I'll wait 'til my simpler methods fail before advancing the arms race like that.

Wow! I totally didn't understand the jargon side of things even though I was shocked by just how technical and wide ranging SPAM has gotten. Bastards!

Here is a thought on the multiple-textareas idea, if 2 are hidden by CSS, then if there is content in either of them the comment is spam. Since the script won't know which ones is the real ones you'd be good. I doubt the script would be smart enough to put content in only one of them, but if so, then there is only a 1 in 3 chance of it showing up. So then you add 10 hidden textareas.

Yeah, I guess CSS is
A. pretty standard now, at least for hiding things
B. more non-trivial to parse than, say, javascript, so it might be a while before they can put in the condition "ignore form elements that are hidden or in containers hidden by CSS"
