Repetition

     Why is it that people intend to put emphasis on the importance or urgency on a question or exclamation by placing numerous marks at the end????? stop it!!!!!!! what is the difference between "what?" and "what???". Am I supposed to scream, in seconds, the last word of an exclamation the same number of marks there are? The same principle can be applied to repeating letters in a word for the same emphasis such as saying "Noooooooooo!!!???". The only thing exceeding my indifference to the support of repeating marks is its level of annoyance; deeming it a pet peeve.
