Which term describes the deliberate use of the Internet to harm others in a repeated manner?

The term that best describes the deliberate use of the Internet to harm others in a repeated manner is cyber bullying. Cyber bullying specifically involves aggressive behavior conducted through electronic means, where the intent is to inflict emotional distress on the targeted individual. This behavior is characterized by its repetitive nature and can occur across various platforms such as social media, forums, and messaging services.

While cyber harassment can also involve harmful actions online, it typically refers to a broader range of damaging behaviors that may not necessarily be repeated. Online trolling, on the other hand, often involves provocations intended to elicit reactions rather than a focused campaign of harassment against a specific individual. Digital pranking refers to playful or mischievous actions online, which generally do not carry the same intent to harm. Therefore, cyber bullying most accurately captures the systematic and intentional nature of the repeated harmful actions described in the question.
