Browsing log file of one site that I manage I just discovered that oBot got past my blocking of it in my .htaccess file. Originally I used just the second entry which was written at ^oBot [OR] with other items following, but now I will use two lines as I want to block it starting as User-agent or anywhere in the string thus I have preceeded it with a literal space, and now hope that I will block it whether it uses either format. Log file entry also included herein. - - [28/Sep/2004:03:06:17 -0700] "GET /robots.txt HTTP/1.1" 200 698 "-" "Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0; obot)"

RewriteCond %{HTTP_USER_AGENT} \ oBot [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^oBot [OR]
# ... other entries followed

Hope this helps other people. Note that for the second entry it "could" also have the NC option to catch both upper and lower case.
