In high school they had a few information kiosk computers spread around the various buildings; two in the library, one in the main reception, one in the cafeteria, and one in the mostly unused hallway right outside the computer club room. They were locked down so you could only navigate some intranet pages using a rudimentary on-screen keyboard, with the rest of the hardware in a locked cabinet.

Guess which one got digitally defaced a couple of times each semester. Guess which ones got left alone. Genius move by the IT guy. Every time it happened he would come talk to the club members about the difference between whitehat and blackhat hacking but other than that nobody ever got in trouble.
