Not quite on the same scale but...
We use SharePoint (yes, I know but I inherited it and we're tied to being an MS site anyway). I had one user a few years back who set up email alerts on a Library for All Changes and Send Immediately (contrary to advice otherwise).
He then bulk uploaded a few thousand files (it was the ISO 9000 Library) and wondered why his email on the laptop and Blackberry (I said it was a few years ago) were going mad.
Biting the hand that feeds IT
