If someone sent you an email every day from different email addresses with the same text saying they were going to rape and murder you, and included your home address, pictures of your family and pictures of weapons, that wouldn't bother you?
How do you know there are no real-world consequences? You're just gonna assume it's some 14-year-old kid trolling you and not one of the many insane people in this world who might actually do something? Based on a hunch?
