Once upon a time I registered firstname.lastname@example.org out of necessity for anonymous registration. I forgot about it. After more than a decade, I logged back in and discovered thousands of online identities had accumulated in the email address. I have thousands of identities for all of people's most important accounts; facebook, google, twitter, everything, and all from a specific pool of internet users: users who are entirely unaware of cybersecurity.
This is a true story.
