Yahoo's New Way of Fighting Spam

It's 6:00 in the morning. Okay, I lied. I never get up that early. But it felt like 6am in the morning. I found something in my Yahoo inbox that I wanted to forward to a few friends to share. To be exact, THREE.

I was brought to a page like this:


Aww. I told myself. So Yahoo! is doing something about spam control now. Good for them... The one I got before was nastier than this though...

So I typed in that character string of whatever that I thought I saw.. And..

Hm...

Yeah?! More?

It's 6am! I wasn't awake for this yet!!

So I ended up sending that mail later.. like.. 3 hours later, when I was more awake to recognize those wiggly strings...

Captcha

A captcha (an acronym for "completely automated public Turing test to tell computers and humans apart") is a type of challenge-response test used in computing to determine whether or not the user is human. The term was coined in 2000 by Luis von Ahn, Manuel Blum, and Nicholas J. Hopper of Carnegie Mellon University, and John Langford of IBM. A common type of captcha requires that the user type the letters of a distorted and/or obscured sequence of letters or digits that appears on the screen.
