Robots.txt is an  increasingly important file found on websites that determine whether you permit a website crawler to index your page for search engine optimization. As web-scraping is entirely legal in the US, this is the wild west of scraping and thus I want to keep mu brain and information safe from scraping. 

Fun Fact: Google [open-sourced](https://opensource.googleblog.com/2019/07/googles-robotstxt-parser-is-now-open.html) their [robots.txt parser](https://github.com/google/robotstxt) in 2019 if you want  to see an example of reverse engineering the robots.txt file for search indexing.
