Game developer Robert Yang is protesting Twitch's nudity policy following the ban of his game, Rinse and Repeat, from the streaming service.

Gym shower simulator Rinse and Repeat is the second of Yang's games to be banned from Twitch, joining Cobra Club, which is described as a virtual “dick pic” photo studio.

In a blog post, Yang objected to his games joining other prohibited titles such as Hatred and RapeLay.

"That means Twitch treats my games exactly the same as the disgusting RapeLay, a game that I won't even bother describing here," Yang said.

"This equivocation is offensive to me, when I focus heavily on ideas of consent, boundaries, bodies, and respect in my games."

Yang lamented that sex in video games seems only acceptable when it is used for titillation or crass exploitation, but causes a stir when it is essential to a game's artistic merit.

"Gamers want so desperately for games to function as art, to witness games about the depth of human experience,” Yang wrote.

“And here is Twitch, a crucial platform in games culture that had 44 percent livestreaming market share in 2014, insisting 'NO' – games should only ever snicker about sex and nudity, like some stoned tweens clutching smuggled Hot Pockets in the back of a movie theater.

"The idea that nudity and sex are allowed on Twitch, only when it's tangential and exploitative, is a f*cking disgrace.

“It sends conservative messages for what is allowed to be a 'real game,' and discourages artistic experimentation from developers for fear of being banned from Twitch," he added.

Yang also suggested that the ban of his games was in part due to systematic homophobia in Twitch’s policy.

The official Twitch ruling on nudity in game streaming is that it “can't be a core focus or feature of the game in question... Occurrences in game are okay, so long as you do not make them a primary focus of your stream and only spend as much time as needed in the area to progress the game's story".
