How to kill the social networks.

After being de-friended by three people on Facebook in the past few days I felt very hurt so decided to get some revenge by randomly selecting three other people and de-friending them. Immature, perhaps, but it strikes me that if anyone wanted to destroy social networking the simplest way would be to encourage people to delete three friends at random. This would cause so much ill feeling that the ensuing chaos would cause the networks themselves to collapse along with their privacy issues and advertising income.
