Another issue for those that rely on adwords for traffic, in certain countries brands are able to use their trademarks to prevent certain keywords being bid upon at all, for example this recently happened the keyword "chanel". It's possible many would argue that this is fair enough, but what happens when someone gets Google to bad a fairly common work or something the relates directly to another product.
