Just type the letters you see in the box
CAPTCHAs. You've probably seen them. They're those little boxes that show you a picture with some letters and numbers. You're supposed to type those characters in a box to prove that you're a human leaving a comment on a blog post or news website, and not a spambot.CAPTCHA stands for "Completely Automatied Public Turing test to tell Computers and Humans Apart." And since most websites don't have spam filters analogous to the ones that keep your email box (relatively) clean, they seem like a good idea.
Until you see some really poorly produced CAPTCHAs. You know, the kind that are completely impossible to read. Like the one to the right. Or like the 20 or so found on the Headware Blog. Granted, some of these CAPTCHAs aren't so much difficult to read as incredibly inappropriate. But they do show why sometimes automation is not the answer.
