freecivweb - 2D HTML5 - reCAPTCHA - Invalid domain for site

[axel]

When trying to use the "Forgot password?" or the "New user account" action of the 2D HTML5 game there is a captcha. This captcha cannot be solved because it says: "ERROR for site owner: Invalid domain for site key". Most probably the captcha still expects to belong to the former domain play.freecif.org .

Wait, what, freeciv-web uses Google reCAPTCHA?
That would render Freeciv-web non-free as reCAPTCHA is proprietary software (non-free JavaScript).

Also, I don't trust Google anyway.

I think the reCAPTCHA should be removed or replaced with something unproblematic.
