This kind of data shouldn't be accessible by people who do not own the email address..
Also HIBP has a "domain search" for sysadmins: https://haveibeenpwned.com/DomainSearch
If you just want to check if the passwords of users of your service have been breached, there is a separate API for that: https://haveibeenpwned.com/API/v3#SearchingPwnedPasswordsByR...
Give me your email address and I can know your name + address + phone number + history of old passwords + browsing history and more personal data
But who am I to care about that kind of things, screw people right
Wich explain the lack of care for privacy and security in the west, boy 2024 will be fun..
Privacy washing is a thing apparently
