Let me get it done, I'll secure your website by implementing multi-layered defense mechanisms to block bot traffic and spam submissions without frustrating real users.

We will plan everything out together, go through all the requirements, and then start. 2. Conduct a deep audit of your current forms to identify specific vulnerabilities and capture points used by bots. 3. Integrate Google reCAPTCHA v3 or Turnstile to distinguish between humans and bots seamlessly. 4. Implement server-side rate limiting and honey-pot fields to intercept automated requests before they hit your database. 5. Set up advanced filtering and backend validation using Node.js to block known malicious IP ranges and suspicious submission patterns. 6. Run final security tests to ensure the platform remains fast and accessible for legitimate traffic. Let's talk as soon as possible and get it done. Best Regards, Mihajlo
