title: Bot command returns multiples times
body: <pre><code>    public void onGuildMessageReceived(GuildMessageReceivedEvent e)
     {
        String message = e.getMessage().getContentRaw();
        
            if(message.equalsIgnoreCase(&quot;!hi&quot;)) {
               
                e.getChannel().sendMessage(&quot;Hi&quot;).queue();
            }
            if(message.equalsIgnoreCase(&quot;!hello&quot;)) {

            }
     }

  <p>When I open up my EclipseIDE, run the code, and send a command(!hi, for example) to Discord, it prints normally at first. However, for some reason, it stacks up the message, eventually. What I mean by this is this:</p>
  <p><a href="https://i.stack.imgur.com/a8VQq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/a8VQq.png" alt="enter image description here" /></a></p>
  <p>So now whenever I send a command, it replies multiple times. I don't know if it's a server problem, but it just stacks up. The code I did for the command is shown above. Is there a solution on how to go around this problem? All I did in my 'Main.java' class is add an event listener once for this method's class.</p>
