multiple user account

A sock puppet, sock puppet account, or simply sock is a false online identity used for deceptive purposes. The term originally referred to a hand puppet made from a sock. Sock puppets include online identities created to praise, defend, or support a person or organization, to manipulate public opinion, or to circumvent restrictions such as viewing a social media account that a user is blocked from. Sock puppets are unwelcome in many online communities and forums.
