This game is pretty simple. But I'll explain it anyways.

There is a person above where you're going to post. Your job is to ban them. (not literally)

So for example:

Kirto1452: Banned for blah blah blah.
Tiger: Banned for Not finishing all 100 floors.
Cooldude1: Banned for Not making it to level 200.

So on, so on.
