We're sorry, but access is denied to that document.

This might be because you are accessing this site from a machine in China. Because of a massive amount of robot traffic from Chinese machines, we've had to take the unfortunate step of blocking access from those IPs..

还记得robbin也发过个，说搜索爬虫的帖子，没想到这事俺也遇上了.

ps:没办法只好用代理下了。
