Did this happen maybe when the subdomain was changed from newsgroup.xnview.com to forum.xnview.com? How long ago was that? How many users could not register?

@Pierre: Is reCAPTCHA registered for xnview.com or just the subdomain newsgroup.xnview.com?
https://developers.google.com/recaptcha/docs/domain_validation wrote:A reCAPTCHA key is normally tied to a set of individual domains or package names. For web users, the API key pair is unique to the domains and first-level subdomains that you specify. Specifying more than one domain could come in handy if you serve your website from multiple top level domains.
For example, if you specify the API key pair to yoursite.com, the following table shows whether or not reCAPTCHA will work for the domain and its subdomain variations. If you specify other domain names or TLDs (for example: anothersite.com, yoursite.net), the same reCAPTCHA conditions apply.
https://developers.google.com/recaptcha/docs/settings#main_settings wrote:Your registration is restricted to the domains you enter here, plus any subdomains. In other words, a registration for example.com also registers subdomain.example.com. Changes to this field may take up to 30 minutes to take effect. A valid domain requires a host and must not include any path, port, query or fragment. This does not apply to the reCAPTCHA v2 (Android) site type.
