That sounds right. Though I logged in through my Twitter ID since I'm no longer on FB and it still knows I know MJ. Maybe that's because I once logged in through Facebook once before. I just don't know. One of the real problems about this is you don't know how it works, or how to stop it. I though the Facebook response was very weak.

Like I said. If Facebook convinces the privacy commissioner of Canada they're doing the right thing and I'll go back. Don't see any sign of that.
