title: In bot rewards (discord.py) by voting on top.gg / discordbotlist
body: <p>When a user votes for my bot on either of the sites, it sends them a DM and I want it to do other things too but for the sake of simplicity can we use a <code>print</code> statement to be triggered once the user votes? is this going to be done using webhooks? I'm totally new to those.</p>
  <p>Please give me an example code of how it could be done!</p>
