Maybe he is, but he's just not posting it yet. The hacker(s) probably read these forums aswel. If they feel safe, they'll go through less trouble to cover up I guess.
And you are who defending him the whole time? If he is such a big part of the community why cant he speak for himself and is doing only selective responses?
Assuming and knowing are two different things, and from what i read yet he doesnt get anyone involved into any investigation process, and he himself doesnt seem be able todo it all.
Probably time to contact the Australian Government as someone suggested.
