Which term describes the act of causing emotional distress through multiple contacts?

The term that most accurately describes the act of causing emotional distress through multiple contacts is harassment. Harassment refers to a pattern of behavior that is intended to disturb or upset an individual, often through repeated and unwanted communications or interactions. This behavior can take various forms, such as phone calls, messages, or in-person confrontations, and is characterized by the intention of inflicting emotional harm or distress.

Stalking, while it may involve similar behaviors, is typically defined as a course of conduct directed at a specific person that would cause a reasonable person to feel fear. Stalking often includes a level of intimidation or threat that goes beyond mere emotional distress. Intimidation generally involves instilling fear or apprehension, which is not specifically about causing emotional distress through repeated contacts. Aggravation is a broader term that does not specifically relate to the systematic distress inflicted through multiple interactions. Thus, harassment is the most suitable term, denoting a pattern of behavior aimed at causing emotional distress.
