Use reCaptcha in China

Hi. I come from China. In my country, we are unable to use any of Google’s services, including reCaptcha. But after reviewing the support of reCaptcha, I found a domain name that allows us to use it. It just need change the api from “https://www.google.com/recaptcha/api.js” to “https://www.recaptcha.net/recaptcha/api.js”. How can i change it? Maybe you can add an option to the settings that allows us to choose which link we use?

Sorry, my English is poor. ??
