Facebook revealed, earlier today, that it had detected a data breach affecting at least 50 million accounts (and as many as 90 million). Within minutes, as you might imagine, multiple sites including TNW were rushing stories out to inform everyone. Just as quickly, concerned readers began posting the news, including to the site in question. Now Facebook is actively stopping people from posting those stories.
