The executives confined at the Hole are reported to have numbered up to 100 of the most senior figures in Scientology's management, including the Church of Scientology International's President, Heber Jentzsch. Individuals are said to have spent months or even years there. After a few managed to escape the Hole and Scientology, they gave accounts of their experiences to the media, the courts and the FBI, leading to widespread publicity about the harsh conditions that they had allegedly endured. The Church of Scientology has denied those accounts. It says that "the Hole does not exist and never has" and states that nobody had been held against their will. However, it acknowledges that its members are subjected to " 2religious discipline, a program of ethics and correction entered into voluntarily as part of their religious observances." It has has been described by ex-members comparable to that of a 3North Korean death camp.
