I have the Hide Adult Content checkbox selected in my profile settings, but I am still seeing stuff like this in the sidebar as links to Random Magazines / Posts / Threads.
I'm not sure if it technically is a moderation issue where the Magazine, Post, or Thread needs to be marked as NSFW in case the OP didn't do so or something more. It seems like it happens too often to just be where it is simply posts that slip past the mods so that makes me wonder if the NSFW checkbox is broken or just doesn't do anything.
personally i like the random section and i hope it stays. if anything, an option can be added to hide it for people who dont want it. mag mods need a reminder to have their users mark their posts nsfw
