I have been consuming reddit via the https://www.reddit.com/r/all/gilded/ feed and it is just WILD what kind of weird and worrying stuff is going on.
EDIT: Looks like it was a place to connect opiate buyers and sellers
To my recollection, each post contained replies listing a username and perhaps a region of the state where they were available, and each post had upvotes or downvotes as well as some replies saying how "friendly" each listed username was. All other conversation other than "friends" and ratings seemed to be swiftly deleted and users were encouraged to move to reddit private messages.
At the time reading the content naively I thought it was people looking to use heroin together more safely, but now I'm thinking it was probably people looking for heroin dealers.
Here's a screenshot of the subreddit rules (from Google cache): http://i.imgur.com/2PKOr7B.png
I don't think I took a good screenshot of the forum's contents before it was banned. I think it was active for several years.
Reddit has really gone downhill ever since they turned into a nanny forum where they arbitrary enforce rules.
