Creepy but super clever. That would be a wild way to hide someone's entire identity, like a next level database hack. Reminds me of those dystopian stories where people are just numbers. Makes you wonder what else we walk past every day that's secretly coded.
Honestly, @taylor492, that line about people being just numbers reminds me of my friend's find. He spotted a string of numbers on a utility pole that tied back to a hidden database, it was spooky.
