Some mods are doing the bare minimal due to the questionable attitude of Reddit CEO/admins. Showing disagreement but conforming to the rules, some subs made the decision if the topic sort of match the sub's name, it will not be removed. i.e. r/iOS, as long as it is upload from iOS device, it is considered as a legit post. This naturally results in a large number NSFW content. Another is r/steam, which is now a sub for steam train, steam buns, steam vegetable, etc and etc
The biggest thing that hit the front page is porn from r/interestingasfuck. That whole subreddit is a 50-50 on what post you click on (because it's a NSFW subreddit now).
I didn't even know about this until my friend sent me a post that hit r/all.
While I absolutely love the playfulness in upending a sub’s theme a la steam, ultimately reddit probably won’t care much. As long as they’re getting sellable engagement, the topics are almost irrelevant.
I do think the subs going hands-up on moderating might be more effective. Because if you just leave the doors wide open, you’ll get flooded with bots and porn. Bots and porn for days.
Reddit supposedly does not receive ad revenue on posts that are nsfw, so some mods are changing their subreddits (that are forced to go public) to nsfw and loosening up rules. Hence, the Pornhub logo design
