Removing fans refers to deleting a user from the fan list of his social media platform, that is, he is no longer regarded as his own fan. This means that users will not be able to see your dynamic updates and your interaction will be interrupted. Unsuccessful means to stop paying attention to users' dynamic updates, but it will not be deleted from your fan list. This means that this user can still see your dynamic updates, but you will no longer receive their dynamic update notifications. By removing fans, you can completely get rid of users, and not focusing is a relatively slight way to get rid of them.
