What's the spookiest 'dead' subreddit?

1. /r/OurOverUsedVeins/ A sub for heroin addicts. It got banned and unbanned at some point, its community mostly moved to other subs. Pretty tough stuff to read, keeping in mind that a big part of its former userbase might be dead by now.

2. r/TheGuy People attempting to find out more about this man with strange mouse/human dolls

Most threads were just about confused people what is this place. There was sticky which named users who have been invited on that sub. After a week/month I got kicked from there and new wave of users were invited there. That was weird af
