Recent Followers are accounts who have followed you. They are arranged chronologically, starting from the most recent.
Use this feature to view these accounts and Follow them back or Blacklist them. You also have the option of directly tweeting out to these accounts by using the Reply button.
Where do I find the Recent Followers for my Twitter account?
You'll find your Recent Followers within the Manage tab on Crowdfire. The Manage tab is situated on the top bar (web app) or the bottom bar (phone app)
