can't use google.com/recaptha/ in china

[CN-Phska2008]

Most of my users are in mainland china, so they can't use "google.com" for recaptcha , can you make a version that replace "google.com/recaptcha" to "recaptcha.net/recaptcha/" because recaptcha.net can be load in China, thanks

我的大部分用户都在中国大陆，而因政策问题我们访问不了google.com域名的服务，所以请问您可不可以出一个把google.com替换成recaptha.net，因为recaptha.net能在中国大陆访问，多谢
