Thailand's Ministry of Culture warned women this weekend that “underboob selfies”—the practice of taking a photo of the lower half of your breasts—are verboten.

The news was first published by local daily paper Thai Rath and then posted again in English on ThaiVisa.com . Thailand's Culture Watch Office reportedly said that posting underboob selfies where they could be freely available online violates Thailand's Computer Crimes Act of 2007.

Section 14 of Thailand's Computer Crimes Act says that a person who uploads “any computer data of a pornographic nature that is publicly accessible” could face “imprisonment for not more than five years or a fine of not more than one hundred thousand baht or both.” (A fine of 100,000 baht is roughly $3,035.)

Reuters later confirmed the reports, speaking to ministry spokesman Anandha Chouchoti, who admitted that it may be difficult to enforce the rules. "When people take these 'underboob selfies' no one can see their faces," Chouchoti told Reuters. "So it's like, we don't know who these belong to, and it encourages others to do the same.”

“We can only warn people to not take it up,” he continued. “They are inappropriate actions."

Thailand's Ministry of Culture is particularly stringent and has been criticized for overzealous censorship of movies and music. Before the country's 2014 military coup, the Thai government had banned Bitcoin, Uber, and a dictator-simulator game called Tropico 5. On its English language website, the ministry articulates one of its stated goals that “the general public should be good and possess ethical values while taking pride in Thai culture and applying religious principles in their daily life. They should also possess creativity and appreciate aesthetics.”

According to ThaiVisa, Thai Rath also interviewed one of Thailand's Internet idols, Roongtawan Chaiha, “who rose to her fame by posting her own sexy photos on her Munkaw Chaos Girl Facebook fan page.” She apparently told Thai Rath that she doesn't plan to post any underboob selfies, adding that “posting photos partially revealing the breast from the high angle of view is already causing serious trouble for her.”
