I did click the link after writing that knee jerk comment. I think their page does a great job of explaining that pornography is banned but other content that would be considered “NSFW” is allowed but must be marked as “mature”.
I actually feel like it makes the title of the submission inaccurate and my point still stands there.
And porn is the most interesting aspect as it's morality is much more debatable than hate speech, doxing people, etc.
