An act of Moderation over the person/s who are misbehaving. (via banning them)
I had to place a ban cannon on an idiot because he wouldn't stop breaking the forum guidelines.

An extremely versatile weapon used by power administrators to keep the forums free of trolls. It is much stronger than a feebly banhammer, and its awesomeness is so great it has even been ported to games
Then he shot them all with the bancannon
