Online gamers engage in virtual civil disobedience in the realm of Worlds of Warcraft. I don't play, but i find the phenomena fascinating. Also, check the warning text from the admins:

Attention: Gathering on a realm with intent to hinder gameplay is considered griefing and will not be tolerated. If you are here for the Warrior protest, please log off and return to playing on your usual realm.

Minus the game-speak, this sounds exactly like what you hear cops say when people lie down in traffic to protest a war.
