despens: Abusing a computer or a network is a very difficult concept, since both work best if they are imagined without a purpose.
If to accept "abuse", it automatically means that there is a "purposeful" usage of a computer, hence giving in to the current state of controlled environments.
Niko Princen: There's as much purpose to computers as to life. To abuse the networked machine is a way a user can try to set itself free from the "controlled environment" the computer or network was build in without necessarily following the opposite direction of it's creation. Every user is controlled by what it uses. Rules of usage don't need a purpose. Abnormal use is outside the system. It's unseen, without balance, alone, impossible.
