As preparations for what are essentially terrorist operations can raise suspicions, typically over one's lack of money or time spent away from friends and family, Breivik suggests that "using social taboos is an extremely effective method from preventing people who know you well from digging too much." One such taboo is an obsession with World of Warcraft.
"F[or] example, tell them that you have started to play World of Warcraft or any other online MMO game and that you wish to focus on this for the next months/year," Breivik writes. "This "new project" can justify isolation and people will understand somewhat why you are not answering your phone over long periods. Tell them that you are completely hooked on the game (raiding dungeons etc)."
Ergo, all WoW players are terrorists.
