Cyberstalking and cyberbullying are malicious online behaviors, but they differ primarily in intent and persistence. Cyberstalking involves persistent, unwanted attention towards an individual, often alongside surveillance and monitoring. You can prevent cyberstalking by following the best security and privacy practices. Cyberbullying, on the other hand, is the use of electronic communication to bully someone. This might involve spreading rumors and making threats towards the victim, but not necessarily with the persistent harassment and monitoring often seen in cyberstalking.
