Issue with reCaptcha, SPAM users using contact formular

[mihessel]

Hi prestashop Forum,
After buying and installing the module "reCaptcha" from https://addons.prestashop.com/en/website-security-access/42438-recaptcha-google-anti-spam.html
I still have major issue with reCAPTCHA, I got SPAM from robots/services using my contact formular to sent SPAM.
I'll see continued email creations in the prestashop backend, 15 a minute from IP. 

The module don't block spam, tested both v. 2 and v.3, the spammer/robot/service uses the contact formular to sent spam, and this is not blocked by reCAPTCHA. Are there anyone with the same issue on is this module.

Example of user created: 
Name: 网址①⑧⑧⑦点top注册送⑧彩金
Last name: 存五十送③⑦彩金
email: [email protected]
IP: 38.12.30.33 

Purchased module/software:
reCaptcha - Google Anti Spam module, version: v1.1.7
reCaptcha versions tested with no luck: v2 and v3
Change 'Site key' and 'Secret key' but with same result.

My prestashop version: 1.7.6.8
ReCaptcha anti-spam - PrestaShop module configuration in backend, ReCaptcha allowed score is set to 0.1

Temporary solution is to block the formular in the .htaccess with following.

# blocking contact formular
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{QUERY_STRING} ^create_account=1.* [NC]
RewriteRule ^(.*)$ - [F,L]
</IfModule>

<IfModule mod_rewrite.c>
<IfModule mod_env.c>
SetEnv HTTP_MOD_REWRITE On
</IfModule>
RewriteEngine on
