IMHO thats a horrible idea. If you respond each time you receive a PM, I can flood you off the server. I connect with 15 different bots each of which messages you every 5 seconds. My bots don't get disconnected because it is once every 5 seconds, however you will get disconnected since you'll be sending a message once every .3 seconds. So you'll be first "lagged" by the server to try and stop your flooding, then eventually you'll be killed. I really don't think thats a good idea at all.
