What term is used for a pattern of two or more instances of unwanted communication?

The term that encompasses a pattern of two or more instances of unwanted communication is stalking. Stalking is defined by the repeated and persistent targeting of an individual, usually involving unwanted attention and communication that can create a sense of fear or distress in the victim. This behavior goes beyond casual interactions and involves a pattern of behavior that is intrusive and distressing.

Harassment generally refers to a broader category of unwelcome conduct that can include a variety of verbal, physical, or visual actions that create an intimidating or hostile environment. While it may involve unwanted communication, it does not specifically emphasize the pattern aspect as much as stalking does.

Bullying typically involves repeated aggressive behavior that is intentional and is directed at a specific individual, often in a context such as schools or workplaces. It can take various forms, including verbal, social, and physical bullying.

Cyberbullying specifically pertains to harassment or bullying that occurs through digital platforms. It involves the same elements of unwanted communication but is limited to online interactions.

In summary, stalking is the most accurate term to describe a situation where an individual experiences a pattern of unwanted communication that causes distress and is characterized by the repeated nature of the behavior.
