deathde-snoomentsuspension, I guess this shit is up to you guys to figure out if your post is NSFW or not. I mean… It says in at least one place that profanity should be marked NSFW… But then the admins have been telling people it doesn’t… So who knows… Admins, if you’d like us to mark the subreddit as NSFW we are more than happy to comply =)

While I haven’t touched Reddit since the blackout, I believe the reason people did the John Oliver thing was in the hopes he talks about it since he has a reputation for siding with the people vs. the corporations.
