When we are reporting an abuse, normally we won't know what will happen and in some cases we might receive a private message from the moderators regarding to the status of the abuse.
It would have been nice like to have a notification showing status of reported abuse after review like explaining whether it has been removed, not removed and the reason why it has not been removed. This will help us to understand what reports should be submitted and this could be optional like we could enable or disable the notification.
