In 2009, a collective of net-artists came up with a novel idea: a service to delete virtual identities. The group, Worm Collective, called it the Web 2.0 Suicide Machine. In the first month, nearly 1,000 people used the service to commit virtual suicide. It works like this: after you give the service your login details, it will systematically go through your account, deleting your friends, your posts, removing you from groups and so on. It will also change your profile photo to memorialise your “death”. It is available for Facebook, Twitter, Myspace and Linkedin.
