Facebook Used by Courts to Find Those Who Are ‘Only Online’ - Businessweek: "In March, Hilary Thorpe, a lawyer in East Sussex, England, persuaded a British court to allow her to serve a woman solely through her Facebook account, after showing that calls, faxes and visits had failed to track her down.
The people in both the U.K. and Australian cases were successfully notified in the eyes of the court, the lawyers said. Tsirimokos said that “within a day” of sending the notice, the recipient’s privacy settings in the Australian case were tightened, showing the debtors got the notice. MKM won a court order and then seized and sold the house."
