The image above is a CAPTCHA — you can read it, but computers have a harder time interpreting the letters. We tried to make it hard for computers to recognize because we wanted to give humans the scoop first, but we're happy to announce to everybody now that Google has acquired reCAPTCHA, a company that provides CAPTCHAs to help protect more than 100,000 websites from spam and fraud.

Great choice from Google! reCaptcha is since years a high quality, safe captcha services. Every form which becomes a victim of spam was safe after reCaptcha was added. Plus this captcha image is one you can reallt read if you're an human :)
