Cyberstalkers and trolls across the pond haz a sad:

Websites to be forced to identify trolls under new measures

Last week, a British woman won a court order forcing Facebook to identify users who had harassed her.

Nicola Brookes had been falsely branded a paedophile and drug dealer by users - known as trolls - on Facebook.

Facebook, which did not contest the order, will now reveal the IP addresses of people who had abused her so she can prosecute them.
