The female co-founder of South Korea’s largest porn site has been jailed following months of mounting public fury over the spread of secretly filmed spycam pornography.

Tens of thousands of women have rallied in recent months against the growing phenomenon of spycam videos, known in Korean as “molka”, which mostly involve men filming women without their consent in toilets, changing rooms and in public.

Soranet – which had more than a million users until it was shut down in 2016 amid widespread outrage – carried thousands of such clips among reams of other X-rated content.

Producing and circulating all forms of pornography is illegal in South Korea.

The site’s female owner, surnamed Song, was sentenced to four years in prison and fined 1.4 billion won ($1.25 million) on Wednesday for aiding and abetting the distribution of obscene material, including sex videos featuring minors.

The 45-year-old, who founded Soranet in 1999 with her husband and two others, “seriously damaged and distorted people’s universal dignity and value”, said a court statement.
