VAPTCHA is a highly secure smart CAPTCHA with no limit on the amount of verification, but the standard version(SV) can only be bound one domain name to each VAPTCHA unit. The following is a way to bypass the restriction. It has been configured and can be used directly. The demo is the invisible mode, check the official docs for other modes.
