The incident I remember was a locker was auctioned off for non-payment, and bodies were found. It turned out that a husband killed his wife and kid(s), and remarried. Eventually, the new wife took over the bill paying, and didn't recognize the storage charges, so she stopped paying.
Perhaps it would be a good Company policy if freezers were not allowed to be stored in lockers - or in a special location that is accessible for inspection by Company personnel.
The issue of privacy is a non starter. If you want to keep your personal items in a storage locker - there is no need for a freezer. You hunters can keep your kills at home.
Not to mention terrorists.
