Answers - Similar Nickname/Display Name
Due to the popularity of certain aliases and the large number of Yahoo! users, similar nicknames or display names may occasionally be found. Sometimes, there may be very subtle differences; however, there may be times where the same names are used by multiple people.
While our policies allow duplicate display names, if you believe that another user is impersonating you or that their actions are violating the Yahoo! Terms of Service, please contact us with specific examples of the offending content. Please also include references to your own information which corresponds to the content you are reporting so that we can look into this matter for you.
