I'm pretty sure it's normal for someone to defend themselves when accused.
I meant the way you're defending yourself. Saying, "oh, I was just showing off a bug", doesn't really work. You were exploiting that bug multiple times, regardless of how much time it took up. If you just repeated yourself a couple of times through chat and then let the host know what was wrong after that, that would have been OK, but you went to the extreme.
Also, you were votekicked (cringe) out of the server, so that shows people didn't like what you did and wanted you out of the server.
