Ninjalante

One who is covert & skilled in the ways of attaining justice, esp. via internet protocol & social networking sites.

A ninjalante is a person who walks a fine line with the law in order to exact what they believe to be justice from criminals, because they think that the criminal will not be caught or will not be sufficiently punished by the legal system.
