Topic: Suspiciously high numbers of page views have stopped - here is why

For about a week this forum experienced a sudden spike in both page views and visitors shown here.
The interesting thing was that only a few topics were viewed while many others were not.
In particular all Ron Paul topics, video and documentaries topics - not much else.
In one Ron Paul topic we got about 500 page views per day.

I used Awstats to process my logfile and it only showed a dozen visitors or so which one would expect in a new forum with few users yet.
I also eventually got Google analytics to work and it agreed more or less with Awstats.

I just figures out what happened. A look at my raw logfiles revealed that I was visited by the Chinese/Japanese search engine Baidu specifically its robot: Baiduspider every few seconds or so! it kept changing IP addresses too.
Upon creating the robot.txt file with

User-agent: Baiduspider
Disallow: /

the number of visitor fell from about 7 to 3. Upon blocking the IP range - it went down to near zero... what a relieve :)
I find it interesting that only topics that affected US foreign politics were spidered so intensely. I have seen at list one poster in a different forum who complained the baidu only spidered his index page - well, his forum was about software.
I have copied below the info on the baiduspider, in particular the ip range may of interest for someone with similar problems.

I spent some time to see if there is a way to reduce the unnecessarily high frequency of visits by that spider and found the following:

User-agent: Googlebot
Crawl-delay: 5

This will limit Googlebot requests rate to 1 per 5 seconds.

As I would not mind being spidered but perhaps once a day would be enough.

I have now completely blocked the spider with an IP block but might try the delay option one day or manually allow the baiduspider every now and then. Pitty I had to block it.
