What term describes a person who commits the crime of stalking in cyberspace?

The term that specifically refers to a person who commits the crime of stalking in cyberspace is "cyber stalker." This designation highlights the behavior of repeatedly and intentionally following or harassing another individual online in a manner that instills fear or distress.

Cyberstalking can involve various forms of harassment, such as sending threatening emails, posting unwanted messages on social media, or using technology to trace a person's online activities without their consent. The defining characteristic of a cyber stalker is the persistence and malicious intent to intrude into someone's online life, mirroring the real-world concept of stalking but adapted to the digital environment.

While the other options may describe behaviors around online aggression or crime, they do not specifically convey the same meaning as cyber stalking. For example, a cyber bully usually engages in intimidation or harassment through digital platforms but may not necessarily involve the persistent nature of stalking. Similarly, a cyber criminal refers to individuals who commit various types of crimes online, which could be broader than just stalking, and a cyber harasser might refer to anyone who harasses online, not exclusively within the context of stalking. The specificity of "cyber stalker" is what correctly identifies the act of stalking in the digital realm.
