Re: Freedom-hating assholes
The rule itself is a delightful catch-all:
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.
So, say/do something that offends any portion of the public and you're out. So basically a contractual term that can be applied to anyone, as it is unlikely that when anyone says pretty much anything it won't offend some group of twats on the internet.
