body: <p>I know <a href="https://developer.mozilla.org/en-US/docs/DOM/document.write" rel="noreferrer"><code>document.write</code></a> is considered bad practice; and I'm hoping to compile a list of reasons to submit to a 3rd party vendor as to why they shouldn't use <code>document.write</code> in implementations of their analytics code.</p>
  
  <p>Please include your reason for claiming <code>document.write</code> as a bad practice below.</p>
