The dndmemes protests were a pretty incredible thing while they lasted. The mods changed the subreddit to “nsfw” because that disabled most of the monetization. Then Reddit admins told them the subreddit obviously wasn’t really nsfw and to change it to accurately reflect the subreddit content.

…so the mods changed the subreddit rules to allow actual nsfw content and people went nuts. In multiple senses of the term.

Of course “accurately reflecting the subreddit” wasn’t what Reddit really cared about. They wanted to preserve the advertising stream for a popular subreddit, and this did the opposite of that. Reddit admins soon after basically said “remove nsfw content, restore the subreddit to what it used to be, do what we say or we’ll replace you with a mod team of our own choosing”.
