We found a group that matches the name of one of our Action Alerts. It's in the Group Type of Advocacy Participants. Are these groups being created by an admin, or by the system?
When an Action Alert is created, a corresponding group is created by the system which contains all of the constituents who take action on that alert. The system uses these groups for metrics and reporting in other areas of the application. These types of groups and others like it can not be deleted.
