Ghost followers are users on social media accounts who do not interact with other accounts. These followers ignore common online activities, such as liking or commenting on a post. Social media platforms, such as Twitter and Instagram, tend to have the most ghost followers.
Services are available for users to purchase more followers for their online account. By having more followers on their account, users intend to create the illusion of having a popular account. Ghost followers can be removed by going into the account and blocking the user. As of 2014, smartphone applications are also available to help users determine if they have inactive, or ghost, followers.
