Question

Do you see the same things I see? The glimpses of the flag hidden away? (link)

Hint

What part of the website could tell you where the creator doesn't want you to look?

Solution

going to the site, we will be able to see

index.html

Mr. Robots
HELLO FRIEND

given the hints above, we visit /robots.txt to see if there any sites that the creator does not want us to know about

robots.txt

User-agent: *
Disallow: /143ce.html

now we go to 143ce.html

143ce.html

Mr. Robots
So much depends upon a red flag
