While some narcissists may use social networking excessively, it's not accurate to say that all narcissists are addicted to social networking. Narcissism is a personality trait characterized by an inflated sense of self-importance, a need for admiration, and a lack of empathy. Social networking can provide a platform for narcissists to display their self-importance and seek admiration, but it does not necessarily mean they are addicted to it.

Addiction is a complex disorder characterized by compulsive engagement in a particular behavior or substance despite negative consequences. For someone to be considered addicted to social networking, they would need to exhibit a pattern of excessive use, withdrawal symptoms when not using it, and continued use despite negative impacts on their personal, social, or professional life.

While some narcissists may engage in excessive social media use as a means of attention-seeking or self-validation, not all narcissists will develop an addiction to social networking. Individual differences, such as personality traits, coping mechanisms, and life circumstances, play significant roles in the development of addiction.
