As I dont read or speak Chinese, a colleague of mine loosely translated this article for me at Sina.com: http://tech.sina.com.cn/i/2006-04-06/0238892442.shtml
Mr. Huang, who has been using Adwords since 2004, normally pays 158 RMB per month. However, on 1/26/06, his Adwords charges suddenly run up to 8,000 RMB.
He sent an email to Google China and asked for investigation. Google replied that there was nothing wrong with the clicks and had no suspicion of click fraud. He then asked Google to provide supportive data and Google declined. He’s going to file a lawsuit, which will be the first lawsuit against Google in China.
