title: AttributeError: 'filter' object has no attribute 'append'
body: <p>I've been making this simple reddit bot, and it worked fine while I was testing it, but now for some reason it keeps giving me this:</p>
  
  <pre><code>Traceback (most recent call last):
    File "conniptions.py", line 49, in &lt;module&gt;
      run_bot(r, comments_replied_to)
    File "conniptions.py", line 24, in run_bot
      comments_replied_to.append(comment.id)
  AttributeError: 'filter' object has no attribute 'append'
  </code></pre>
  
  <p>Here's my code: <a href="https://hastebin.com/usokoyojig.py" rel="nofollow noreferrer">https://hastebin.com/usokoyojig.py</a></p>
  
  <p>Any help would be greatly appreciated, I've been trying to solve this for a while but I'm very new in Python so I have run out of ideas.</p>
