Via Tikirobot, reCAPTCHA. Brilliant:

Over 60 million CAPTCHAs are solved every day by people around the world. reCAPTCHA channels this human effort into helping to digitize books from the Internet Archive. When you solve a reCAPTCHA, you help preserve literature by deciphering a word that was not readable by computers.

Why didn’t I think of that?

    It looks like there’s a NOSCRIPT alternative; I suppose the truly paranoid could just use the NOSCRIPT version, albeit with potentially a bit less security.
