1) Get his IP from the logs and identify whether he is using a proxy, if not we can identify who he actually is. 2) If that fails look back on past confrontations with the people he wants banned and try to find a correspondance. 3) Get a fingerprint of his typing style and identify posts made from aliases. 4) Identify links between the names and the person.
