So Angwe was just a fluke? I highly doubt it. I do agree that people who are using this mechanic to grief others purely for the sake of griefing aren't violating any technical parts of the ToS. They're violating one of those "spirit of the game" sections that is deliberately vague so that Blizzard can run the asshats out of town on a rail.
