[NFBCS] Automatic Captcha solving

[Jonesy Cee]

Not all captcha are Google either. Some just flat don’t have an audio or accessibility option. This is another reason I am looking for a script or plug-in to automate it with OCR.

These applications, scripts and services definitely exist. Just not sure as to the accessibility of them.
