What's with the mostly nsfw content? Was that part of the r/celebrities protest?
For some of the subreddits this isn't as far fetched as for others; /r/videos is more of a work to rule to protest given they're now taking swearing very seriously. You have to think of the 14 year old kids that use reddit.
Or they understood it mean something larger and, as every 14 yo on earth, they will happily comply and never open content which is marked "please do not open if you are not an adult".
