"Big List" of Former Members Who Have Spoken Out

Chanology Anons have been compiling an extensive wiki-based list of people who left the official Church of Scientology organization and have spoken out publicly against it. Although some of them still believe in the validity of the core precepts and practice them outside of the Church of Scientology, all of them have public denounced the legitimacy of the organization itself using their own name.
The purpose of this list is to give courage to others who are still in to finally leave, or those who have already left to speak out. In addition, perhaps those that are still in may recognize a name they may have known before and are unaware they have left. It is also important to show how extensive this list is, especially now that some senior former members have come forward.
Scientology - Through the Door Interviews

The interview includes a few simple questions and the gathered responses are available online. Available questionnaires include a general interview with over 300 submissions, as well as targeted interviews for Ex-INT Base Staff and victims of Disconnection.
Church of Scientology Exit Survey

This online survey was crafted to respect the real-life experience and current beliefs for both those who continue Scientology practice in some form and those who do not. It was also been designed to maximize its usefulness to a broad range of communities and interests. Our goal was to help paint a more accurate picture reflecting that the doubts current Church of Scientology members struggle with are not only valid - but mutually shared by many former members as well.
