reCAPTCHA v2 on Android, noscript fallback broken

Dear developers of recaptcha, My Android app is Clover (http://bit.ly/19ZgD8I), it's an open-source app for browsing and posting to 4chan. 4chan requires the users to fill in a captcha before posting. ReCAPTCHA v2 has never been "officially" supported on Android by Google. Clover uses the noscript fallback (http://bit.ly/1H6iBOJ) to post, by loading the noscript page and getting the image/token out of the received html. This method has been broken before, but I have always been able to slightly fix it by changing the User Agent and such. A recent change in the noscript fallback of ReCAPTCHA v2 broke the my Android implementation, and my users now see an impossible to solve captcha, instead of something easier to solve (a single word): I never implemented the JavaScript version of Clover because I anticipated it to not work. Can I get any feedback on this? Since the system has been broken in the past, I'd like to use a more reliable method I look forward to your response. -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
