A controversial Mount & Blade: Warband mod called 'Gwangju Running Man' was taken down worldwide by its creator after being accused of historical revisionism.
The mod misrepresented the events of the South Korean Gwangju Uprising and depicted protesters as armed and violent criminals, leading to its removal from Steam Workshop.
Valve clarified that the mod's creator was responsible for its global takedown, while Valve limited access to the mod only in South Korea.
Valve's approach is to allow almost everything on Steam except for illegal or trolling content, with the mod likely falling under the former category in South Korea.
