Well, it is a good way to tell computers and humans apart. Computers can read it, while humans can't. They should reject corectly filled in captchas.

- fosap 14y agoThat's a great idea. If i was ever to create a product for colorblinds only i'd use that.
- ihsw 14y agoIt's not an uncommon strategy (eg: fill up a comment form with hidden but obviously named form fields) and since people won't be filling in those hidden fields then bots will have revealed themselves. This isn't by any means a complete solution however it does catch 90% of drive-by spam.
- philipDS 14y agoYup, this is also known as the Honeypot Captcha technique: http://haacked.com/archive/2007/09/11/honeypot-captcha.aspx http://haacked.com/archive/2007/09/11/honeypot-captcha.aspx
- dEnigma 14y agoThat's an interesting approach, but I guess as soon as it would become mainstream, the bots would adapt without many problems.
- NickNameNick 14y agoDepending on how the fields were hidden, they may need to render and reflow html, css and dom changes by javascript. None of which is all that difficult for a full size browser, but it may be prohibitively resource intensive for a high-volume spam bot.
- Bromskloss 14y agoLynx. :-(
- eli 14y agoCareful! There are legitimate toolbars that will helpfully prefill forms, sometimes even hidden fields. I've been bitten by this in production.
- wyck 14y agoWell maybe they are really good and this is a honeypot.

- laurent123456 14y agoYou'd think, but what's so dumb about this captcha is that it's both easy to guess for a computer, but for a human too. If you look at it, the random parts are outside the readable text (which is just white on a gray background). I'd love to know what led to the "decision" of implementing something so dumb.
- fakeer 14y agoI still loathe reCAPTCHA more than any other captcha out there. I've given up hopes of logging in on many occasions simply because of it. Looks like it's designed for not to be deciphered either by humans or computers.
- reeses 14y agoIt started so well, as a tool to harness collective 'intelligence' to digitize text while preventing spam. Now you're right, even the bloody accessible (audio) versions are useless. It's as if a dozen poltergeists are whispering in your ear, and you have to pick out the one that matters.
- kristofferR 14y agoI actually think reCAPTCHA has gotten quite good actually after they switched one of the words to a street address. Just look at the examples in this post, most are pretty easy to decode right away. http://techcrunch.com/2012/03/29/google-now-using-recaptcha-to-decode-street-view-addresses/ http://techcrunch.com/2012/03/29/google-now-using-recaptcha-...
- senthilnayagam 14y agoI totally agree, see this recaptcha which is upside down, how are we supposed to read it http://postimg.org/image/7xgovvhij/ http://postimg.org/image/7xgovvhij/
