Facebook took official precautions against two accounts thought to be maintained by the North Korean government but later discovered be run by regime supporters in China and Japan.
"If a person poses as a person or entity that you don't officially represent, that becomes a violation of our policy," Facebook spokeswoman Kumiko Hidaka told The Washington Post. "Facebook is based on real people that are on there making connections and people are going to get the most value of the site if they're using real identities."
The Facebook pages, along with accounts discovered on Twitter and YouTube, resulted in a media blitz claiming that North Korean had started to utilize social-media outlets as part of its propaganda war.
South Korea had responded to the accounts' discovery by blocking its citizens' access to them, according to the country's official communications commission. The two countries have existed in what amounts to a state of war since the 1940s.
