HI,
I post a blog in my blog with many links to my another site (wiki)
here is the post http://blog.bigreat.org/2006/06/16/the-gre-words-my-robot-failed-to-find-in-webster/

And when I analyze the access log of the wiki, I found thousands of line like this,
208.113.157.151 - - [16/Jun/2006:08:20:34 -0700] “HEAD /Drenched HTTP/1.1” 200 0 “-” "WordPress/2.0.3"
208.113.157.151 - - [16/Jun/2006:08:20:37 -0700] “HEAD /elated HTTP/1.1” 200 0 “-” "WordPress/2.0.3"
208.113.157.151 - - [16/Jun/2006:08:20:37 -0700] “HEAD /Elated HTTP/1.1” 200 0 “-” "WordPress/2.0.3"
208.113.157.151 - - [16/Jun/2006:08:20:40 -0700] “HEAD /enamored HTTP/1.1” 200 0 “-” "WordPress/2.0.3"
208.113.157.151 - - [16/Jun/2006:08:20:38 -0700] “GET /remains HTTP/1.1” 200 5 “-” “WordPress/2.0.3”

why my blog crawling my wiki site without end?

help!

Thanks
