title: Discord bot check if a bot deleted a message
body: <p>I want to make my discord bot to send a reply message only if a user has deleted a message (not bots). I'm using <code>message.author.bot</code> to find out, but it seems that deleting messages isn't the same. So far I have this:</p>
  
  <pre class="lang-python3 prettyprint-override"><code>@client.event
  async def on_message_delete(message):
    if message.author.bot:
      return
    await client.send_message(message.channel, "&lt;@{}&gt;'s message was deleted".format(message.author.id))
  </code></pre>
