Sorry to post this thread twice. It just that, nobody answer my question yet (in another forum's topic). I thought i might posting it in wrong topic.
Can anyone teach me how to decaptcha?
I'm trying to use it with autohotkey for auto click in surf bar in traffic exchange program. Is it possible this way?
I know some people said using OCR, but how to use it to decaptcha? Can anyone help explaining this...
Please don't banned me, if this kind of posting, didnt allow.
Thanks in a bunch! |

| Well it seems noone has experience coding decapcha here, neither do I, but if i wanted to do it I would just do alot of research on OCR, starting by being able to read simple text and moving on to the more convoluted stuff. |

Best solution:

Human solvers
CAPTCHA is vulnerable to a relay attack that uses humans to solve the puzzles. One approach involves relaying the puzzles to a group of human operators who can solve CAPTCHAs. In this scheme, a computer fills out a form and when it reaches a CAPTCHA, it gives the CAPTCHA to the human operator to solve.
Another variation of this technique involves copying the CAPTCHA images and using them as CAPTCHAs for a high-traffic site owned by the attacker. With enough traffic, the attacker can get a solution to the CAPTCHA puzzle in time to relay it back to the target site.[21] In October 2007, a piece of malware appeared in the wild which enticed users to solve CAPTCHAs in order to see progressively further into a series of striptease images.[22][23]
These methods have been used by spammers to set up thousands of accounts on free email services such as Gmail and Yahoo!. [24] Since Gmail and Yahoo! are unlikely to be blacklisted by anti-spam systems, spam sent through these compromised accounts is less likely to be blocked.
