This is a utility rather than a bot.

• Give it the permalink or the id number of a thread. If you hit Enter without typing anything, it will take whatever is in your clipboard.

• It finds the submission object, and pulls all of the root comments.

• They are put into a .txt file with the oldest comment at the top, numbered starting from 1. Multiple comments by the same user will not be considered.

• The report will suggest a random user to you, but you could use Random.org for true-random instead.

Gathering the comments can take a very long time on big threads. In order to ensure fairness, the script will grab every single comment in the thread. Every time you see the "load more comments" button in a thread, that's where the bot needs to spend an additional 2 seconds to get them. Just let it run.
