The police arrested a Park, 35, and 12 others for pornography, Tuesday.
Park masterminded the whole process, according to the police.
DIY (do-it-yourself) was what got his content popular, the police said.
He received orders through e-mail and gave the payers what they had asked for, they added.
He put up internet pop-up ads to fetch a group of 20-40-year-old females to act.
Housewives, office workers, nurses, and private institute owners were all among the actors, and they were arrested.
A total of 180,000 clips were produced and distributed online, netting them 350 million won ($314,000).
He split the money, took 40 percent of the total _ 140 million won ($125,000) _ and gave the women the rest, the police said.
