Tools like this are trivial to make and it's trivial to do it manually using Google. I don't see any point in getting angry about the existence of tools like that, as it's beyond anyone's power to stop people from doxxing each other.
I did something similar to this for a hackathon in university. Obviously not as sophisticated as this, but the concept is trivial. If you know enough about the command line to install it, you can build it.
