> 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, in addition to other remedies which may be provided for under the Handbook and Blizzard’s Website Terms.
