One punctuation mark is enough!

This is just a quick rant so that I can vent some frustration. Why do people feel it is necessary to put more than one question mark or exclamation point after a question or comment?

Seriously, why?

I keep getting emails and attachments that have stuff like "I did this a while ago and now it's different???? Why isn't it like it used to be??? Shouldn't it be doing x, y, and z??!?!?!?!!?!???!?!?" good grief people, I get it already, you're asking a question.

Should I start responding like this: "It because we spec changed,,,,,,,,,, and said to do it a different way............... If you would read the spec then you would know that already!!!!!!!!!!!!!!" ?

I swear, it's driving me nucking futs. If you're doing this, please, for the love, stop it.
