That was on my mind as well. The pessimist in me was concerned that this article will either get /r/opiates banned or will become a honeypot for law enforcement.

What took place in /r/opiaterollcall and why was it banned?

EDIT: Looks like it was a place to connect opiate buyers and sellers

When I stumbled across it a month ago by following a user's comment history, it looked like a very sparsely populated forum with monthly posts in each US state offering information about "friends" in each state or region.

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.

Drug culture and drug markets are two completely different ball games. Banning the latter is hardly inconsistent behavior.

I remembered when I joined, /r/marijuana was a default subreddit...
