I have had "180.76.*" in my IP blocking list for months, yet I'm still pounded by guests from this subnet. Is there something wrong with how I have the IP blocked?

IP Blocking does not prevent access to your forum. It blocks anyone using that IP from Registering, Posting, or Sending Private messages in your forum.

Baidu is a Chinese search engine and is bigger than Google in Asia and as China has the biggest population in the world, preventing Baidu from indexing your website could stop allot of people finding your website.

As Baidu is a legitimate serach engine like Google, Bing, or Yahoo, they do respect robot.txt files, so if you want to stop Baiduspider indexing your website create a robot.txt file and place it in your websites root with the following:-

#Baiduspider
User-agent: Baiduspider
Disallow: /

#Others
User-agent: *
Disallow: /

I have too many spammers from China on my forum and have no interest in foreign traffic. I'll try the robots.txt file. If that doesn't work, I'll filter them in IIS or the firewall.

Thank you for the info.

Will that robot.txt file understand the name of Baidu since the forum "active users" says unknown search robot" I take it that internally, Baidu knows who it is and will obey when it sees that line with its name?
I agree, out of 120 guests, often half are that spider, and since our cars were never sold in China, and we'll never have Asian members - blocking them is just fine with me.
I see dozens of "active users" with this address pattern at any given time 180.76*
