wikijack 

When an over zealous fanboy hijacks and changes information in certain wikipedia articles to defame, libel, or completely destroy someone.

This can also apply to anyone that randomly goes on wikipedia, chooses a random, non-protected wikipedia article, and edits it completely without anyone's consent.

In other words, people that get joy from editing wiki articles to fit their own destructive/sick goals.

A combination of the words wikipedia and hi-jack.

"Wow, I didn't know that Bob Saget is a convicted sex-offender!"

"Someone must have wikijacked that article."
