What does cyberstalker mean?
A cyberstalker is a person who uses the internet and related technologies — email, social media, messaging apps, spyware, or location data — to pursue, monitor, or harass another person repeatedly and unwantedly. Unlike a cyberbully, whose attacks may be episodic or directed at many targets, a cyberstalker fixates on one victim over time, often using anonymity and multiple accounts to sustain contact while evading detection. The behaviour can include sending threats, spreading false information about the target, impersonating them online, or tracking their physical movements through digital footprints. The word emerged in the 1990s as personal computing spread, combining 'cyber-', the prefix associated with computer networks and cyberspace, with the older noun 'stalker'. It appears most often in news reporting, legal proceedings, and online-safety guidance, and it carries unambiguously negative connotations. Many jurisdictions have enacted anti-stalking statutes that expressly cover conduct conducted through electronic means.

Etymology of cyberstalker
Cyberstalker is a compound of 'cyber-', a prefix popularised in the late 20th century from 'cybernetics', the science of control systems coined by Norbert Wiener in 1948 from Greek 'kybernetes' meaning steersman or governor, and 'stalker', an agent noun formed from the verb 'to stalk'. As internet use expanded rapidly in the early-to-mid 1990s, the prefix was attached to existing words describing antisocial behaviour, giving rise to terms such as 'cyberbully' alongside 'cyberstalker'. The word entered mainstream usage through journalism and early legislation on online harassment during that decade.
How cyberstalker is actually used
The word carries strongly negative connotations and is used almost exclusively in legal, journalistic, and safety-advice contexts. It is a countable noun with the standard plural 'cyberstalkers'. Because stalking is defined by persistence rather than a single act, applying the term to someone who sends one unpleasant message is generally considered an overstatement.
Easily confused with cyberstalker
A cyberbully generally engages in one-off or repeated hostile acts intended to intimidate, often among peers, whereas a cyberstalker systematically pursues and monitors a specific victim over time, producing sustained fear.
