I believe these people are trying to pose as Donald Trump and say he is going to have me killed. I know this is not Donald Trump but it is mob and other organized crime groups that are trying to use him to threaten people or to communicate with people with out anyone seeing it but you or the people they want to pass a message.
Note I have personally researched some people communications in this method and they where obviously criminals. This is troubling as they seem to be teaching this to criminals or people that teach it to criminals.
