title: Make a user give custom blacklisted words discordjs
body: <p>I'm making a bot and I want the user to be able to give their own custom filtered words that contains profanity:</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>//declare profanities
  let Blacklist = ['bad', 'bad2', 'bad3']
  
    //profanity: deletes messages and DM's users
    for(let word of Blacklist){
      if(message.content.toLowerCase().includes(word)){
        message.delete()
        message.author.send("Keep the use of Profanity out of our server!")
        break;
        }
    }</code></pre>
  </div>
  </div>
  </p>
  <p>How do I go by making the users add their own words to the array just by inputting it on discord</p>
