When individuals make impacts, it's completely optional to verify. In the case impacts do need to be verified, there are 3 states to inform the administrator the state of the impact.
Pending: Is when the impact is in a holding pattern and the administrator who is supposed to verify has not verified it.
Verified: When the impact is approved, vouched or "verified". Administrators can verify an impact by agreeing to the notification when someone makes an impact. This can also be done by logging and navigating to "Manage Impacts" to verify the impacts.
Disputed: When an impact is incorrect and the administrator decides to not update the details or believes this is incorrect. The administrator has abilities to provide the reason for the dispute.
