### Explanation A person's name is not just a label but a crucial part of their human identity, playing a significant role in social interactions, culture, and self-perception. Names give people individuality and allow society to function. Even before the advent of the Internet, people actively used nicknames and call signs as alternatives to obvious official names from passports. However, social networks, and in particular, the ability to have multiple alternative accounts, have allowed people to create new identities without limits and, along with them, use a variety of different nicknames. ### Examples - [How Unique and Traceable are Usernames?](https://arxiv.org/pdf/1101.5578.pdf) ### Types - behavioural - technical ### See also - [[SOWEL-6.
