"Web 2.0 Suicide Machine collects login credentials, which is a violation of our Statement of Rights and Responsibilities (SRR)," it said.
Featuring a noose on its homepage, 'Web 2.0 Suicide Machine' deletes profiles, friends, including other information on Facebook, MySpace, Twitter and LinkedIn for users based on their account information.
