title: Why every web site coder doesn't use DNT?
body: <p>I am a coder who codes html, css and js. Also, I am an internet surfer.</p>
  <p>A lot of webpages ask me &quot;can I collect your data?&quot; with pop-ups. Then, I have to dismiss them every time. In my webpage, I follow browser <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/DNT" rel="nofollow noreferrer">DNT(DO NOT TRACK)</a> setting. However, why everybody doesn't?</p>
  <p>DNT is easy to call, just <code>console.log(navigator.doNotTrack);</code>.</p>
