Why should we believe and listen to the threats of every jerk who threatens to do something against another user?
Here on the forum, no one knows anyone. Why be afraid of simple letters and not a person? Because the one who threatens is just letters on a screen. The rudeness that some users show only suggests that most likely in life these people are deeply unhappy, and they are trying to somehow make up for the humiliation from others offline, here on the forum.
If users know each other in real life, then for sure they will take their relationship offline.
