Today I want to make a few remarks about NSWF boards: Either you make them NSFW and then go with it and deal with what "free speech" gives you or you limit the use - but then it's not NSFW. WAKAchan's /b/ annoys the hell out of me right now because it can neither decide on what it wants to be (thus it lacks a basic form of sincerity) and the users' constant whining about some content being "not random enough" reminds me of when 4chan went down and the /b/tards started posting 4chan NETA pics on 5chan's random board, eliciting the same kind of comments and outrage from the whiney 5chan folk.
/b/ or "Random" should stand for mayhem, melodrama, disgust and bewilderment. Any attempts at restricting and taming this spirit will neccessarily result in something else and most likely in something lamer than what the random boards on 4chan, Futaba, Siokara, etc. are like. My advice for WAKAchan is to simply admit that their /b/ is not meant to be NSFW and just go with that. At least that would be an honest attitude.
