5449721 story US Marine Corps Bans Social Networking Sites 202 Posted by Soulskill on Wednesday August 05, 2009 @08:34AM from the don't-ask-don't-tweet dept. Q-Hack! writes "Citing security concerns, the United States Marine Corps has issued an order banning access to social networking sites like Facebook, MySpace and Twitter on its network for the next year. The Pentagon is now reviewing its social networking policy for the entire Department of Defense, which should be completed by the end of September, according to a report from CNN. The policy for the entire military is somewhat fragmented, as the Army ordered military bases to allow access to social media sites in May."
