A face only a bot could loveSure, Microsoft Research's spot-the-kitty game is a cute way to make people prove they're not bots (instead of making them read a twisted jumble of letters). But it's no match for the delightfully cruel Hot Captcha: Look at nine people, and pick the three hot ones. Hot Captcha works by grabbing photos from the classic site Hot or Not that are rated very hot or very, um, not. So forget all you learned from Dove's Real Beauty Campaign and click on someone pretty. — NICK DOUGLAS
