Just discovered that admins are removing resource-content on the subreddit. Both the DPRK and China megathreads that are in the sidebar have been removed, probably others too.
I doubt this is unique to only /r/communism, /r/communism101 is probably going to be hit as well.
Ah, I haven't seen a justification for it yet, not that they really need to give one. They did the chapo banwave with a "both sides" argument. What I can tell you is that the megathread was originally posted by one u/albanianbolshevik (see here) and that that account has been "suspended" (which I think means banned by the admins) see here. TBH for all we know, it could have simply been automatically removed due to the user's ban.
Content posted by banned users doesn't get removed when the user is banned.
Damn dude albanianbolshevik was a great poster.
