Chess.com has a funny secret literally written into its code

A little bit of context:

Websites have what is called a robots.txt file. It can be accessed by typing in the URL, followed by /robots.txt - For example, google.com/robots.txt would take you to google.com's robots.txt file. The purpose of a robots.txt file is to tell search engine crawlers (the things that find websites to show you when you search for something on the internet) what pages of the website should and shouldn't show up in search engines, and which search engine crawlers can show what. If this doesn't make sense, go to this Wikipedia article and it should sound less dumb.

Chess.com has a secret image built into their robots.txt file, you can view it here (scroll down a bit) or just see this image:

Not sure why I needed to share this with you, but here you go.
