Is The CAPTCHA Broken?

Here's an interesting post from Coding Horror. Basically, describing whether the CAPTCHA is broken or if designers are just using sloppy methods. What I find interesting is software utilities designed to "break" the CAPTCHA. Looking at that post, Google, Yahoo! and Hotmail have unbroken CAPTCHAs. So, if the CAPTCHA was broken, I guess my question would be, why would Google, Yahoo! and Hotmail be using them? Apparently, they know how to do it right. Google also shows that a CAPTCHA can be effective yet readable.

Anyway, interesting read. Thought I'd share. Being a programmer, I can appreciate the nature of that post.

    Well, you also have those guys who use questions like what color are green apples ?
    Seems like spam-bots can't guess what the answer is 😉

    I really like reCAPTCHA, from a Google guy and ex-Mono guy.

    We've found that even using a captcha (reCAPTCHA) our sites will still get several hundred spam a week. Spammers are using automated human-powered captcha breaking services. These services pay a certain amount per broken captcha.

    The Internet sucks.

    Perhaps you think the internet sucks now, imagine when you lose your vision how awesome these captchas become. Some people are working towards making captchas ineffective simply for accessibility reasons.

    Current CAPTCHA is definately broken and getting harder and harder for REAL PEOPLE to pass. I've just created a beta CAPTCHA service that I'd like to have tested by those who enjoy breaking security software. Any takers? Documentation To directly play with it from a browser use

    I'd like to avoid the Predicted SPAM Tsunami any ideas to make this service better and easier to use would be welcome.
