When Equifax had a major leak exposing personal information of millions of Americans I sent them a notice to permanently remove my data from use. To be clear, my Equifax score IS NOT frozen, it doesn't exist altogether.
I'm still fucking pissed about that. All of their equipment should have been confiscated, securely erased, and melted down. Then we should have sent them a bill for disposing of that data securely, and a massive (like billion dollar) fine for fucking up that badly.
