The FreeBSD ports package 'py-recaptcha' says that you need to obtain a key from http://recaptcha.net/api/getkey. Unfortunately, that URL and shorter variations on it just return 404. That domain is served by Google but appears to be empty. There's certainly nothing there anymore. Apparently you now have to sign up with Google and get a private key from the Google developers program.
Why is nothing simple anymore? - Brian
