And according to the first British study into cyber-stalking, around 35 percent of victims are now men, and all cases are virtually committed by women.

Dr Emma Short, a psychologist at the University of Bedfordshire, has had hundreds of responses to an online survey as part of her research with the Network for Surviving Stalking.
