Why block_phone_customers is rated Medium
This tool modifies customer records by blocking/upserting phone numbers. While potentially reversible (upsert implies create or update), it restricts customer access which has significant business impact. It is a Write operation (upsert = insert or update), not Destructive since data is not deleted. High severity because misuse could block legitimate customers at scale.
