The reCAPTCHA v2 came out in December 2014.
It is no longer possible to obtain new v1 API keys.
We need to obtain/rewrite a new API layer for reCAPTCHA.
See https://developers.google.com/recaptcha/docs/faq#what-happens-to-recaptcha-v1 for information.
V1 isn't going away, but it's going to get harder and harder to actually use it because API keys are no longer given out.
