Don't know. But my story is: About 32 years ago I played Tank Wars, where we all had tanks in a maze and tried to blast each other. It could only be played around lunch time on Friday, as it used up most of the power of our university mainframe.
People tended to use mildly obscene names. One day someone closed a port without logging off, and the university registrar got that port next and found himself in the raunchy scoreboard. That was the end of Tank Wars.
One lollipop to anyone who can name the university and one of the screen names.
