Reddit banned the subreddit where users could ask questions about safely using darkweb markets and receive answers from informed Redditors. One of the most popular things from that subreddit was the DNM Buyers Bible. The most recent copy is available on this site.
Many users only used the darknetmarketsnoobs subreddit for access to the DNM Buyer’s Bible. I have uploaded a copy here: DNM Bible.
Credit for creating and backing up the bible go to Dread users /u/PacketsAndPuns and /u/murderhomelesspeople.
