Isn’t your (and everyone else’s) address public information anyways in your country?
Here you can search for whoever and find their full name, address, and a bunch for information. If you pay a small sum to a company (or call the tax agency yourself for free, but that’s annoying) you can also find out how much money someone is earning.
Almost every phone number is also available and searchable online.
All this information is also available if you for example know the car plate number of someone’s car.
