Random Website: You need to set up #2FA with your phone number!
Me: Why?
Website: In case we get hacked!
Me: I don't really care, no one even knows about this account and it doesn't have my personal information.
Website: You misunderstand, it's so that in case we get hacked, we HAVE your information to leak to the hackers. They worked hard and deserve it! Also we sell your account to ad companies but they're not interested unless they can tie it to a real person.
