Teenagers have been taking photos of their bodies and selling them for extra pocket money, raising alarms over the morality of the younger generation.
What started out as something done for fun has developed into a part-time business involving even elementary school students who take photos of specific parts of their bodies for sale.
Most of these photos, which began circulating in 2011, are distributed at cafes.
On the Internet, there are hundreds of web pages. The price of the photos varies depending on the parts of the body for which they are taken. The photos carry specific price tags. Most of them are traded for 500-1,500 won (45 cents-$1.3) but they can be much more expensive.
The trading of photos goes beyond simple distribution. Buyers often make explicit demands on what they want along with the crudest of sexual jokes.
In some cases, these exchanges lead to buyers asking for actual meetings, some of which are believed to have led sexual abuses, leading the authorities to investigate the foundation of such developments.
Those caught distributing these photos are subject to a maximum jail term of one year or a fine of 10 million won ($9,000)
