If their so good at hacking i.e. "look what I can do", why not turn their talent to do some good like developing a few B4PPC app's and then they can share them with us if they want to show off.
Is there a possibility that any of the code samples or app's could have been infected with a virus etc. It's just that recently my ISP was attacked, along with stealing a load of email addresses, a Trojan was also planted in a jpeg file.
