A friend of mine recently got her Gmail account "hacked" because of a weak password (the same as her login..).
While sanitizing her account, I removed the forwarding of her emails to one email address (let's say email@example.com). I typed the scammer's email in a search engine, and I found one domain name which seems to be related to him/her.
The Registrant, Administrative contact, and Technical contact use this email address, and the postal address is filled with plausible data.
Are these informations reliable ?
