Well, if he is hacking computers over network, then bravo, never thought he'd be smart enough. And for the others who let their computers get hacked by Tim, haha, never thought they'd let someone like him hack it.
But really, being hacked is something to take up with your firewall/anti-virus. I highly doubt that Tim could ever hack anyone like people believe he can (without them knowing). He's just using little internet tricks if anything.
If people still believe he hacks computers then don't download anything from him, don't direct connect with him, and don't go to any of his website links.... tada
