There is nothing on this page

When inspecting the source, there is a comment leaving a vague hint: No more information leaks!! Not even Google will find it this time…
My first instinct was this must be a robots.txt challenge, as it typically bars users from certain webpages. Inputting it into the URL, it leads us to a page with: User-agent: * Disallow: /s3cr3t/

And when appending /s3cr3t to the end of the URL, the password is revealed in users.txt
