Will this stop all spam messages?

Probably not. But it should reduce it.

Is it GDPR ready?

Yes, the plugin does not set any cookies nor does it send any data to external servers. All required data is stored in your database. The IP based
spam protection uses a one way encryption to protect the website from bots. The used keys for the encryption will be recreated every 2 month.
The stored, encrypted data will be removed automatically every 2 month.

Do I need coding skills?

No, everything can be managed from the WordPress Dashboard. Just enable the required functions and enjoy it.
