This scam wouldn't have been possible if the scammer couldn't easily look up someone's name, pay a few dollars, and see where they live, their phone numbers, email addresses, and family members. It's not as much of a problem in Europe because of the GDPR, but in France their government cybersecurity is nonexistant so everything has been breached repeatedly so it's the same effect.
It's insane this type of data broker hasn't been banned and why I will never register to vote.
Every piece of data you give away is a liability, not just for the services tracking you, which some people might defend, but for cybercrime and data breaches.
