I once set my facebook email as a super old hotmail address all the way back from high school. I wanted all the notification spam sent to an email I would never check. I later get a "suggestion" to friend a very random person with a vaguely familiar name who I have 0 mutual friends with.
The name was an alumini of a college I didn't go to, who I once emailed to setup an admissions interview with.
Facebook clearly has already been scraping email headers (or at least had an agreement with microsoft to do so).
Yes, I can confirm Facebook does this. When you import your email address book, Facebook stores it forever.
I don't know if they keep your credentials around, too, and periodically refresh their data. That'd be doubly invasive, but it wouldn't surprise me. :)
that would make sense. because the timing happened when I switched it to the ancient hotmail address, it could have his imported data still stored and rechecked to find my old email where it hadnt before.
