"Removal of user accounts
Once created, user accounts will not be removed. It may be possible
for a username to be changed (depending on the policies of your local
wiki). The Wikimedia Foundation does not guarantee that a name will be
changed on request.
Whether specific user information is deleted is dependant on the
deletion policies of the project that contains the information." -
