Answer:
Sock puppet
Step-by-step explanation:
A sock puppet, a reference to a puppet created by placing a sock over one's hand, is a misleading or fake online identity created to promote a particular point of view, often in praise of a firm, organization, product, or individual; to manipulate public opinion or to argue, bully or review products. Regardless of the purpose it was created for, sock puppets are rarely welcome in online communities and forums.
