Oh yes, very occasionally it's been an ad, or at least mass media output - even when I recall who posted it it's hard to find.
They probably already record every item displayed on screen (and how long for, and whether my cursor hovered it, etc.) so a list of items I saw (on any device) in the chronological order I saw them should just be a simple db lookup away.
The model they currently use serves two goals: to extort money from fanpages, and to hook users up by intermittent reinforcement.
