Well, they already root around... That's why they can serve contextual ads.

Right now it's "harmless"... But people get a lot more personal in email or google searches than they do on, say, facebook.

There's some gold to be mined in there.

All it takes is one idiot in middle management that thinks "who's going to notice if we just ...". Like the recent Mocality case.

Which was rectified within a week, no?

I don't doubt you; this may eventually happen, but for the meantime, I'm trusting them (over my ISP, anyway), with my email and backing up/saving the stuff that warrants it.
