We’ve added new features to help you manage your Fortnite Communities https://communities.epicgames.com/
*Assign Team Roles
Community owners can now assign roles to trusted team members to participate as moderators and help manage their communities. Navigate to Community Settings > Team to get started.
*Ban Users
You can also now issue temporary or permanent bans for users. To ban a user, click the three-dots menu next to their post and select Ban. Once banned, users cannot post or reply in your community.
