I disagree about "quite" since almost every game mechanical statement in it is incorrect. I'd suggest focusing on the lack of social rules in the game, which allow for completely unrestricted scams, corporate espionage and treachery.

It might end up illustrating the opposite point though, since players who lose everything to these scams are often surprised and driven away, which is the opposite of what social networks want. In comparison, the possibility of losing a ship to a pirate is pretty clearly advertised.

To complete the analogy, I would think social networks should try to prevent the dogpiling and cancelation effect that shock and destroy people, while allowing them to be occasionally exposed to different opinions. Unfortunately it seems the opposite is more often the case, as in EVE.
