Blocking Non-US Yahoo Bots

Anyway to Block Yahoo China and Other Non-US Searches?

[vphoner]

I would like Yahoo to index my site for US ONLY search engine. But I noticed in my logs that Yahoo China was indexing my site, which I definitely don't want. All my sales are U.S. based, so anything other than Yahoo.com
I don't want. Is there any code you can put in robots.txt to block only the foreign robots? I will need this for google as well. But I still want to allow the regular google and yahoo (which is generally what people use mostly in the USA).

make a robots.txt for your site and block them

Hi, can you block say just the foreign YAHOO bots but allow the U.S. Yahoo bot? If so, how will I find the total list of bots to block? Is there a command that will only allow U.S. Bots?
