    I have a set of some captcha breakers for different captchas. Some sites use those default captchas (e.g. the pligg default captcha), others not, and those I want to solve with decaptcher.

    How can I know which captcha do I have? So: what could be a good fingerprint? Histogram etc, does anybody know?

    I want to use it to spam forums and wrote my own phpbb submitter because I am so tired of XRumer. 100k captchas daily though cost some money.

    But what I found out just now: you can tell gocr the accuracy, so maybe gocr itself knows well if it can recognize the captcha or not?
