I deleted facebook in 2008, this article discusses shadow profiles.... I suspect that more people deleting facebook and moving to facebook owned subsidiaries, or anything that is centrally owned and not federated will not solve the problem. even then there will be new mining techniques with their own set of challenges.
unfortunately I do not think that more people doing that will solve the root of the problem... only try to treat a symptom.
