Humor: The 10.5 most stupidest captchas on the web

link to Flickr imageCaptchas have been around now for a few years but still some web sites use them more as a Darwin award then a Turing test.

For them it seems that captchas help to keep traffic from annoying passers-by at a minimum.

Here is our collection of the funniest, most unusual or plain unusable captchas – 10.5 ways to assure that (almost ) nobody will be able to access your web site.

1. The Matrix captcha

Well known for its strong access control and nearly insolubility. Can be further tightened with Chinese, Japanese or Sanskrit characters.

2. Einstein’s portal

This one exists in multiple variations. Unresolvable or nonsense equations and some you can actually crack with the Google calculator (if you can’t find your Math PhD documents at that very moment).

3. The Rorschach test

The Rorschach captchas have dual functionality build-in. First they allow to test the personality characteristics and emotional functioning of potential users for your web site, and secondly they are excellent for testing the patience of visitors. Use more than one within a single data entry process and the popularity of your web site is guaranteed.

5. The Chess Master’s revenge

  8. link to article
    In the best tradition of the “dadaist” nihilistic movement from the 1920s, these sites don’t exactly do anything or provide any useful information – in short they are a bit pointless.

    Remember what the “first web cam” was used for – to monitor a coffee pot. Yes that’s the spirit.

    Let’s create an art out of this….
