title: Block bingbot from crawling my site
body: <p>I would like t completely block bing from crawling my site for now (its attacking my site at an alarming rate (500GB of data a month).</p>
  
  <p>I have 1000 sub domains added to bing webmaster tools so i cant go and set each one's crawl rate.
  I have tried blocking it using robots.txt but its not working
  here is my robots.txt</p>
  
  <pre><code># robots.txt 
  User-agent: *
  Disallow:
  Disallow: *.axd
  Disallow: /cgi-bin/
  Disallow: /member
  Disallow: bingbot
  User-agent: ia_archiver
  Disallow: /
  </code></pre>
