I'm more shocked that there were 57 million accounts for Hot Topic. People. Stop giving your information to companies that have nothing to do with your personal data.
The optimist in me would like to think that a significant portion of them would be ‘dead’ emails, as kids would have used cringey addresses like [email protected] (I know I did! 😅); but honestly - given how pervasively online Gen Z/A are (and relatively tech illiterate), they’re probably almost all valid addresses.
