Link…The personal details of more than 100 million Facebook users have been harvested and published on the net.
Ron Bowles, an online security consultant, used a simple piece of code to collect the data from Facebook.
The list, which has been shared as a downloadable file, contains the URL of every searchable Facebook user's profile, their name and unique ID.
In a web post, Mr Bowles said he published the information to highlight privacy issues.
The file has spread rapidly across the net.
On the Pirate Bay, the world's biggest file-sharing website, the list was being distributed and downloaded by more than 1,000 users.
One user, going by the name of lusifer69, described the list as "awesome and a little terrifying".
In a statement to BBC News, Facebook said that the information in the list was already freely available online.
