Cyberstalking is the specific use of electronics (usually the internet) to control, track, and spy on another person, group of people or even companies. Whilst it may seem like a relatively recent phenomenon the term can be traced back to the nineties. Cyberstalking is hugely prevalent, with a study in the United States from 2009 showing that one in four stalking victims had also been cyberstalked as well.
