In response, Blizzard Entertainment announced that Chung had fallen afoul of its rules, which state: "Engaging in any act that, in Blizzard's sole discretion, brings you into public disrepute, offends a portion or group of the public, or otherwise damages Blizzard image will result in removal from Grandmasters and reduction of the player's prize total to $0 USD."
"Effective immediately, Blitzchung is removed from Grandmasters and will receive no prizing for Grandmasters Season 2," Blizzard said in a statement. "Additionally, Blitzchung is ineligible to participate in Hearthstone esports for 12 months beginning from Oct. 5th, 2019 and extending to Oct. 5th, 2020." The company's Chinese social media accounts added the sentence, "We will, as always, resolutely safeguard the country's dignity."
