php - Google ReCaptacha validation

Question

I have this google captcha V2 in my registration form and it works but it also let's quite a lot of spammers trough all the time. Anyone got any idea how to make the validation stronger? i tried to add site verification(expected hostname) and other parameters but i just ends up breakinging it as soon as i try to modify something so it do not work at all.

if (isset($_POST['g-recaptcha-response'])) {
            require('component/recaptcha/src/autoload.php');
            $recaptcha = new ReCaptchaReCaptcha(SECRET_KEY, new ReCaptchaRequestMethodSocketPost());
            $resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);
              if (!$resp->isSuccess()) {
                            setError(t("invalid_captcha", "Captcha confirmation is invalid."));
              }
    }
