title: Do you know bot LTX71? What is it doing? Is it spam?
body: <p>There is a bot/spider crawling my websites very fast. The useragent is 'ltx71 - (<a href="http://ltx71.com/" rel="noreferrer">http://ltx71.com/</a>)' and it has serval ips:</p>
  
  <p>52.3.127.144 and 
  52.3.105.23</p>
  
  <p>On the website it says just this:</p>
  
  <blockquote>
    <p>LTX71</p>
    
    <p>We continuously scan the internet for security research purposes. Our
    crawling is not malicious and only notes summary information for a
    page.</p>
    
    <p>If you have further questions please contact research@ltx71.com</p>
  </blockquote>
  
  <p>I'm wondering what research purposes. I cannot find anything about it on Google. Should i block this bot? </p>
