What is a "backdoor" exactly? Another euphemism used to disguise something much darker I imagine. Usually a "backdoor" is something you would be aware of in your home.

This is more like your landlord giving the keys to a stranger who comes and stares at you every night when you're sleeping and rifles through your draws and cabinets.
