“The one with the smallest buttocks has to drink, on a viewer vote.”



Three men and three women dance and show off their behinds in front of the camera as part of an internet broadcast.



The drinking game is followed by the gang hosting variety of risque games and conversations with none of the profanity or sexual content being edited out.



The show by BJ -- broadcasting jockey -- Chulgoo is part of a growing fad for “makjang” entertainment, a Korean slang term for anything deemed to have gone “too far.”

The term has an added significance when used in the context of scarcely-regulated internet broadcasting. These shows are popular for their raucous entertainment value, but often test the limits of their platform operators’ -- and the public’s -- tolerance with their tendency to go beyond South Korea’s broadcasting norms.



On TV and radio, content such as sexual games, drinking and the use of expletives is subject to regulation by the Korean Communications Standards Commission, which can review content in advance. But this is not possible with live internet platforms.



Authorities can make suggestions to remove certain content, but the ultimate decision on what to put on their websites and how to restrict access to minors is mostly left to the operators of the platforms themselves.



Chulgoo, who has 727 million accumulated views on Korean live broadcasting platform Afreeca TV and over half a million subscribers on YouTube, is no stranger to online controversy -- he received fierce criticism this year for describing the May 18 Democratic Uprising as a riot.



But other users have gone far beyond this into violent, misogynistic threats.



Shin Tae-il is famous for his pranks on unsuspecting pedestrians, especially elementary school children. In one recent video, he drove into a gas station and asked for 10 won ($0.10) worth of gas.



Although the videos seem obnoxious and pointless, there is a clear objective -- getting as many donations and views as possible.



Afreeca TV channels make money from viewer donations, but broadcast jockeys such as Chulgoo make more money by re-uploading their content to YouTube. According to the Multi Channel Network Association, the estimated revenue per YouTube view is 1.2 won.



But his videos have sometimes gone beyond mostly harmless attention-seeking and simple pranks, into situations that require police intervention.



In August, an anonymous female YouTuber God Gun-bae touched a nerve among male viewers with derogatory comments about men. Shin revealed a picture of a woman who he claimed was the female broadcaster -- illegal in itself without her permission or good cause -- and said he would kill her, as well as issuing threats of sexual violence.
