They aren't tricks. Inviting your a friend to Facebook via. email isn't a trick, and keeping a record of it so that Facebook can notify both parties that the request has been accepted isn't a trick, for example.

It's still, nevertheless, far less than what people put on Facebook themselves. It might be comparable to me asking my friend about this person I saw the other day. Her friends are giving me that information. Though, as the person, I wouldn't appreciate my information shared, it's something that happens often in the real world, not just Facebook.
