I don't think one can break a scale-free network like that of Facebook by playing the same game as Facebook.

One way to counter a scale-free network is to create adjacent scale-free networks that replaces its competition one part at a time. This is what, I believe, WhatsApp (with messaging) and Instagram (with images) were on the verge of doing.
