Usenet > DDL > Private > Public
Usenet is the easiest to automate. I can set it and forget it. For DDL, I use two private sites so I know the quality of what I'm getting. Private I need to worry about ratio, but quality will be more controlled than public.
The Amber Room on Telegram is the spiritual successor to The Trove that is actively updated. I can confirm it does have the World of Darkness books.
