 KEDA will block all incoming changes to `ScaledObject` that don't match these rules:
 
+- The scaled workload (`scaledobject.spec.scaleTargetRef`) is not found.
 - The scaled workload (`scaledobject.spec.scaleTargetRef`) is already autoscaled by another other sources (other ScaledObject or HPA).
 - CPU and/or Memory trigger are used and the scaled workload doesn't have the requests defined. **This rule doesn't apply to all the workload types, only to `Deployment` and `StatefulSet`.**
