A woman who co-founded Soranet, South Korea’s largest pornography website, has been sentenced to four years in prison for aiding the distribution of obscene material.

It is illegal to produce and disseminate porn in South Korea.

The site had over a million members at its height, and tens of thousands of illegal porn videos, including spycam and revenge porn.

"Beyond the basic concept of pornography, the website severely violated and distorted the values and dignity of children and youths as well as all human beings," the court said.
