Something that's worked well for me on my blog (although it doesn't stop 100% of spam) is to require the user to tick a checkbox before submitting the comment. You have it box unticked by default but you can include a bit of JavaScript to autotick it once the page has loaded, so the majority of users don't need to do anything.

The Recaptcha device specifically also provides an audio test. But point taken, even so it could prevent accessibility challenges. Nevertheless, when my system is currently receiving around one software powered spam per minute, I need a quick pre-built drop-in solution to this; I don't have time to write my own AI! If you have any other free or affordable pre-built drop-in solutions to spam protection to suggest, this would be a great forum to do so! My particular situation isn't even a web forum---it's a comment form that does nothing but send email to librarians. But the spam bots don't know that, and are sending 1 spam per minute to it. "Pre-moderation" is not a solution; that's what we're doing now, but we can't afford to hire an FTE just to seperate our actual user feedback from spam!
