I figured out fairly early on in my support career that getting dumped on was more likely (and more vicious) the less the user knew about the technology, and the less responsibility they took to make sure they'd done all that was required of them.
It's like a contract - we'll do everything we can to ensure your data and info is safe, and you do everything YOU can to let us do what WE do best - keep things running.
Unfortunately, end users who understood the technology (and it's limitations, in the extreme case) were few and far between. Most just wanted to vent because they felt guilty for not backing up/copying/using passwords/whatever properly, and we were the lucky recipients.
I realised later that most people are bastard-coated bastards with a bastard filling.
