100 million Facebook users had their details published on file-sharing websites and torrents this week.
"As I thought more about it and talked to other people, I realised that this is a scary privacy issue," said Ron Bowes in a post on his website. Mr Bowes is the IT security consultant who wrote a piece of software that accumulated all the publicly available data on Facebook and put it together in one place for people to download.
"No private data is available or has been compromised," Facebook said in a statement. "Similar to a phone book, this is the information available to enable people to find each other, which is the reason people join Facebook."
