There always has been a lack of a mechanism to test the quality of fans or people liking your Facebook page. Only demographic information like age, sex and location were available to page admins. There has been no measure provided by Facebook until now to differentiate between valuable fans and irrelevant fans for page admins.
Keeping this issue in mind, Facebook has included option to list down valuable and irrelevant fans separately in page settings to help page admins to keep their page free of litter and to keep it fresh with valuable content which is useful to valuable fans.
But there is a catch to this update. If you remove a user from the page then it will automatically move the user to irrelevant fan list. This can make it difficult for admins to pick irrelevant fans.
