Dear All,

I seriously love captcha and as a developer I find comfort in them in protecting my app from spam!
Sometimes some captcha make sense such as this one.

I just hope all sites follows thru with the sample captcha above.

...on the other hand, I seriously dislike captcha such as these.



It is seriously a pain in the eye. (especially to non-technical person and elderly one..)

How about you, do you have some favorite captcha?

Thoughts?

Captcha's do not provide 100% protection against automated bots. Many captcha's, even ones that seem very hard, have been cracked. The Coding Horror blog has a number of articles about this. See for example CAPTCHA is Dead, Long Live CAPTCHA!

Apparently there are smart hackers who know how to write software to recognize the letters in a captcha, even if the letters are (almost) unreadable by a human being.

The Daily WTF also has some funny articles about CAPTCHA failures:
