Yes, that's my point in the article, but sometimes people's definition of "porn" goes too far. On certain networks you could be banned for posting an image of "L'Origine du monde" an oil-on-canvas painted by French artist Gustave Courbet in 1866, that hangs in Musée d'Orsay, Paris.
In Europe, they don't have a problem with this and seed the difference between art and porn. Yet, in the USA, things appear to be more prudish. It is in the USA that many of these networks have their headquaters, and so, American morals are exported to the rest of the world.
