Facebook has agreed to tighten privacy controls as part of a settlement with US regulators over abuse of user data. The Federal Trade Commission said Facebook would tighten consent rules on privacy, and close access to deleted accounts in 30 days or less. The case began in 2009, when Facebook changed settings to make public details users may have deemed private. In a blog post, Facebook founder Mark Zuckerberg said the company had made a "bunch of mistakes". - Carl Grint
