China is famous for strict porn ban. Here's the bright example of dangers of being involved in production of adult content.
Female author going under pen name "Tianyi" published an erotic novel called "Occupy" and sold it on Chinese version of Ebay - TaoBao.
After police arrested her, she told that she made about 150 000 yuan (apr. 30K in US dollars) from selling Occupy and other erotic books online.
Her book, featuring a lot of explicit gay sex action gong between teacher and students, was banned soon after arrest.
Long story short, authorities got the writer and four other people involved in production and selling pornographic erotic story.
Author herself got sentenced for 10 years in prison, others got jailed as well, from ten months to ten and a half years as well.

No wonder it's a wicked thing to make living from doing anything sexual in China.
Snitches get huge rewards ($ 118 000 !!!) by government for reporting porn relate content to police.
