The censorship board has nothing to do with obvious violations of the anti-pornography law. It also has nothing to do with prostitution regulation.
What the censorship board used to do was ban books and comics that were not pornographic but offended some people's religions (Satanic Verses was once banned because the chairman of the censorship board was a muslim) and nonsense like that.
They have mostly become nonfunctional. Good riddance to them.
