Cracking is breaking copywrite protction on software. Anyone that says that hacking into a machine and causeing damage is cracking and not hacking, is just trying to justify something. Its one of the oldest arguments in the last 15 years for hackers, and its all the same thing. using the term cracker is, in my opinion, quite stupid if you are talking about unauthorized access to a computer.

And this has been discussed enough on here to make anyon sick.
