Good stuff, Ziroc. Make sure the subnet gets banned too, so that he can't use another computer in his school lab. In a funny sort of way, I would LOVE it if this teenage hacker wannabe tried to log on from his home. Now THAT would be brilliant.
Telstra has very high penalties for this type of stuff in Australia. Bagman if you're reading this, don't screw up your HSC by doing this - your only other option would be to become a toilet cleaner, and I doubt if you would make the grade, mate.
