Ya. They've been hacked. On a few occassions. But I don't think they make it public.

Most of those that ask how to hack hotmail usually follow it with a "because my boyfriend/girlfriend/husband/wife is saying/doing/fooling around with lawyer/my best friend/dumped me" or some variation of that.

I find that many people do not read information that is presented to them. There is a real serious issue on the Internet today with reading comprehension (Yes, I know -- a broad statement but one, I believe, that has a strong ring of truth to it). Our society and those growing up in the present society understand a world where arguments and convincing someone is done in seconds rather than over time. So why read the fine print? Just "gimme, gimme, gimme" a la Homer Simpson.
