This shows that Facebook have already have you as an entity in other people's networks before you have even joined Facebook. I guess you can cement yourself within those networks by adding them as friends, or saying that you know them. I guess they also watch to see who you look up, and from that see if there are any connections between those that you look up, those friends might appear as further recommendations. It can be quite spooky sometimes. The interesting thing with that account is that I never friended anybody, so it's interesting to see who comes up in their list. Some appear quite random, but others I recognize.
