    The captcha here http://traffup.net/login/ it looks like a normal captcha. But the impossible part is you dont need to type the letter highlighted in red.
    I tried deathbycaptcha and decaptcher but no luck. I guess it will only work on manual captcha breaking services?

    Let me know your thoughts.

    DBC/DeCaptcher DO employ manual solvers however they only see the image, they don't see the above text. Therefore they would not ignore the red letter. The only way is if an OCR specific to this CAPTCHA type were developed to ignore the red letter. OR if this CAPTCHA type were so popular that manual solvers of DBC/DeCaptcher recognized the red letter and ignored it. OR if DBC/DeCaptcher manual solvers were trained for this new type of CAPTCHA, to simply ignore the red letter.

    When a captcha is sent to the captcha solvong companies its only the captcha not the other text so I dont think they can unless you contact them and ask them to assign someone directly.

    This is smartly implemented, services like DBC and DeCaptcher should look to resolve this soon.

    Damn, that's smart. Would not be too hard to solve though.

    The weakness in that captcha is that they made the odd letter the same colour every time. To solve, download the image, replace that tone of red with the background colour to make it invisible using imagemagick, and then upload to your captcha service and let them solve it as normal.

    Yup I agree with Autumn - just edit the captcha with imagemagic before sending it -

    Is imagemagick a website where I can upload the image and they will automatically convert it?

    Imagemagick is a command line program for doing automated image manipulation. Very useful for cleaning up captchas, bulk resizing / cropping / watermarking / optimizing pics etc. http://www.imagemagick.org/
