(AP) — In an otherwise innocuous part of Facebook's expansive Silicon Valley campus, a locked door bears a taped-on sign that reads "War Room." Behind the door lies a nerve center the social network has set up to combat fake accounts and bogus news stories ahead of upcoming elections. > Inside the room are dozens of employees staring intently at their monitors while data streams across giant dashboards. On the walls are posters of the sort Facebook frequently uses to caution or exhort its employees. One reads, "Nothing at Facebook is somebody else's problem."
