Captcha Services - Case Sensitive

[Stroks]

Made a yahoo mail creator but the captchas are case sensitive, so I didn't ever get the correct result. Where can I configure a captcha service module to solve captchas case sensitive?

What is the best catcha service for yahoo?

You can set additional parameters from your anticaptcha's provider API here:

Format should be:

parament1=value1&parametr2=value2

and so on
