What is the Captcha for? This is a malicious idea and I have voted to have the question removed.

The basic idea of CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is not to let computers to solve it, so if you can analyse the image by software it is a bad CAPTCHA...
And to be honest, the idea of trying to break it smells wrong - don't go that path!!!

I'm kind of agree, a 5.
I would only add: many implementations of CAPTCHA have been proven to be breakable with the help OCR. Of course, breaking the CAPTCHA is a kind of malicious activity.

My comments above were based on V2 of the question. The intent is unequivocally malicious albeit futile as you suggest.
