CAPTCHA is a test catagory. Not a specific format. The most common CAPTCHA today is the wavy text you see on some sites. The link you posted refers to the CAPTCHA that Yahoo! uses to test for bots.

This does not mean all CATCHA tests are broken.

There is some clever thinking on both sides of the problem.

Porn guys use live people looking at porn to decode CAPTCHA images from a Yahoo! account being created realtime. Then use the Yahoo! account to spam or sell to spammers.

I think it would help if Yahoo! put a message into the image so the porn lookies would at least get an idea of what's going on.
