Hahaha. I did the same thing some ten years ago with a birthday. Nearly lost access to my Playstation account because of it. Finally did lose access when I switched internet providers and the email address that went with it.
But I'm most concerned with social media. That's what truly gets scraped to get the names of kids, your hometown, your past schools, etc. People put out too much real information and that's what gets them to be an open target to scams.
