1 - A symbol of violence and imaginary power over others, used by peniley-challenged jerks, at websites, to make themselves feel better about being so inadequate, and unliked by anybody

2 - a symbol used by bossy creeps at websites, to try and make you "fear their power" you're supposed to imagine they have...but really they have no power..or friends..because they are just assholes.

3 - a picture that should be thrust as far up the offending admin or mods nazi ass as possible, except they'd probably like it

The term 'using the ban hammer' is 'short' for banning someone, if you are an administrator or a moderator. It is more often used at forums.
VocaloidsRule: Hey, have you heard? NinjasRAwesome used the ban hammer on Kailuvshisporn!

KakashiHatake: Oh, what did he do?

VocaloidsRule: Post porn! Couldn't you guess from the name?

A slang term substituted in for banning, or 'exiling' somebody from a chat channel. Also can be removed from other things, such as as a board, forum, team, etc; most often online.

Origins come from Starcraft where moderators were depicted with a hammer or maul as an Icon.
