If you are managing a platform experiencing high-bot traffic, it may be time to audit your security stack. To help you secure your site, I can:
Modern automated tools have turned CAPTCHA solving into a commodity. Hackers use several methods to shout "root me" at a target server: captcha me if you can root me
Bind the CAPTCHA challenge to a specific session, and invalidate it after one use. Prevent replay attacks. If you are managing a platform experiencing high-bot

Example CTF scenario:
While rare in modern professional frameworks, "Security by Obscurity" via frontend validation is still found in legacy systems, IoT device interfaces, and poorly developed internal tools. Understanding that JavaScript can be read and manipulated is the foundation for finding real vulnerabilities like IDOR (Insecure Direct Object References) and XSS (Cross-Site Scripting).
