Easy reCaptcha bypass in User Verfication plugin

If I manually delete div class=g-recaptcha block from page via Inspect Code in browser and click submit button, then reCaptcha check is not performed at all.
Automated scripts that not pass g-recaptcha-response field with POST request can easy register many new users without confirmation.

Please add something like

 if (isset($_POST['g-recaptcha-response'])) {
...
 else {
if ($_SERVER['REQUEST_METHOD'] === 'POST' && $default_registration_page == 'yes') {
$errors->add('loginCaptchaError', $captcha_error);
}
}

to all reCaptcha verification blocks in functions-recaptcha.php.
