Check this out:
https://www.reddit.com/r/pyongyangYeah yeah, it's Reddit, I know. But looks like it's an official DPRK subreddit. Only links posted are those from DPRK news sources, downvotes are disabled, only mods can submit posts and there's propaganda everywhere.
In particular, notice the portraits of the three Kims to the top-right. Is it just me or does Jongun look so inferior compared to his predecessors? Maybe because it's two glorified paintings of manly Korean leaders next to a photograph of some chubby kid with a shit haircut.
I wouldn't usually suspect this of being an official subreddit but the DPRK has in recent years stepped up it's presence on the internet facing outsiders. There's the KFA that's been around for a fair few years with their website and now they've got an official YouTube channel (stimmekoreas), multiple Twitter accounts and even a Facebook page.
So the real question is, how long before they make an official 8ch board? :^)
