When I was in schoola classmate set up an instance that is designed for hacking. But another classmate took it in another direction. Instead of following the clues to the answer (it's a game) they instead hacked the instance and created a folder bomb but named the folders with the Mongolian space separator character. So removing them because a task. No body got upset because well... Hacking can be fun!

Second: hacking is the term used when you break into something to make it better.

Cracking is the term used when you break into things for malicious intent
