Some mods are doing the bare minimal due to the questionable attitude of Reddit CEO/admins. As long as the topic sort of match, it will not be removed. i.e. r/iOS, as long as it is upload from iOS device, it is consider as legit post, which of course results in a lot of NSFW content. Another is r/steam, which is now a sub for steam train, steam buns, steam vegetable, etc and etc
