I came back from a week in DC once and found I had 455 emails, mainly on social nudity and child pornography.
Social nudity I have no problem with, but no way in he11 do I want my computer even remotely connected with child pornography. Even the techies couldn't figure it out. Finally a gal with the email service figured out somehow postings from a couple of chat rooms were being funneled into my email. She got it stopped and all deleted. (I hope). But, that's been about three computers ago.
