Unlike messages on Twitter, Instagram, and Snapchat, there is no filter between your phone and the masses. If someone leaves threatening messages on one of the above platforms, they can be deleted or censored. But a phone number? That is an extreme invasion (not to mention a huge inconvenience), which is exactly why Kardashian did it. He's upset, and wants to hurt the person who upset him. But that is a pathetic excuse for this juvenile situation which only seems to escalate by the minute.
