The Blacklist and Whitelist features help us show results that are customised by you. Whitelist is a list that you create, of users that you do not want to unfollow. These could be celebrities, close friends, perhaps even your family. When you add an account to your Whitelist, we will never suggest that you unfollow them, even if they do not follow you back. (Although you might want to have a little word with Mom about why she isn’t following you back.)
