With the proliferation of Web 2.0 social networking sites like Twitter, Facebook, LinkedIn, and Myspace, sometimes people find it difficult to pull the plug when the decide that they do not want to participate any longer. If you are a budding luddite and decide that you want to remove your presence from the web, you'll find that putting content online is very easy, but removing it can be very difficult. The folks at WORM decided to create program that automates the content removal and account deletion process, but has the unfortunate name "Web 2.0 Suicide Machine". Facebook served them with a cease and desist notice for their service, but they have countered by planning to release a LiveCD that has the same functionality as their website. From their description, this is not a specialized set of software, but a collection of python scripts that automates standard web browser sessions that reduces the time to remove your content (video, pictures, posts, etc.).

Getting rid of all your content can be difficult, as sites such a Spock (now Intellius), Google Buzz and Plaxo mirror your Web 2.0 profiles if you make the connections.
