Do you know recaptcha (http://recaptcha.net)? They say it's safe because their OCR can't read the words. According to the link you gave the method should be really safe.
And if it's defeated it's great because then it's much easier to digitalize books ;)

My experience is that every Captcha can be defeated somehow. It's only a matter of time:
At FLOSS Manuals, we have it so that no edit can "go live" without the approval of the moderator:

Human review seems like the only solution to this never-ending problem.

Hello list,
There are several cases of vandalism at wiki.puredata.info, who takes care about that? They are all at discussion pages. Maybe there should be some kind of Captcha to prevent Bots from Spamming?

Nearly every IP-edit in pdpedia. I would delete them, but I have no admin-account.
