Scan, brute-force or attack anything you do not own.
Mine cryptocurrency. It uses the whole machine and there is one machine.

Resell or share your account, or run a service for other people on it.

Do, gladly
Learn, build, host your pages, run your bots and bouncers within the limits, keep your dotfiles, teach

What happens when something goes wrong
Throttle: network cut to a trickle for 24 hours.
Freeze: the machine is stopped and your files are kept. A person decides this.
Suspend: a 30-day hold, then deletion. A person only.
Ban and delete: immediately, for the things in the list above that warrant it.
