Since January 2021, there have been several migrations from one subreddit to another, due to the old subreddit,Wallstreetbets being taken over by bots.

Yet it is the most commonly mentioned subreddit in the media.
There is a collection of due diligence that has been created by /u/zedinstead - https://fliphtml5.com/bookcase/kosyg - its currently the easiest accessible version outside of Reddit.
The second way of accessing the due diligence is through my very own library of all data and all research that lags by about a week.
You can find the links to the torrent and Resilio archives here. If you do not know how to use Resilio, please read through the documentation - your username that you create will be visible to all users who "sync" the same key.

Instructions for what Resilio is below, and also on their official website.
