The fight against spammers will go on forever. Google has a new way to combat them.
Google today released an update to its reCAPTCHA system that creates different classes of CAPTCHAs for different kinds of users. In short, it makes your life easier if you’re a human, and your work much harder if you’re a bot.

You’ve probably encountered hundreds of these if a site decides to verify whether you’re human or not.
