title: How to block bad unidentified bots crawling my website?
body: <p>How can I resist the bad unidentified bots to crawl my website? Some bad bots whose name is not present in cPanel of Apache are badly accessing my website bandwidth.</p>
  
  <p>I had tried robots.txt on batgap.com/robots.txt and also blocked with .htaccess but there is no improvement in bandwidth usage. I don't know the IP of those bots so unable to block them by IP address. These bots are consuming too much bandwidth of site and hence a result I need to increase it from server.</p>
