Infrequently, you may end up with data you want to get rid of in your nation. Please note: deleting a single person's profile or batch deleting profiles cannot be reversed. 

Sometimes this is Twitter records for a broadcaster you don't want associated with the account, trial data imports, or data that was imported poorly. To delete a bunch of people from your nation at once, you can use advanced search to do things like identify all the people who follow a specific broadcaster on Twitter (People > Advanced search > Name and contact) or who came from a specific import (Advanced search > Origin). Then use a batch action to delete the records that you do not want by clicking the + sign (pictured below), adding them to a list and then deleting them.

A couple of tips:

• If a person has made any donations to your nation, you cannot delete his profile until you delete all donations associated with the person. You can sort donations from Finances > Donations
• Consider making a snapshot backup of your database from Settings > Snapshots before you begin batch deleting, so your nation can be restored if necessary.
