I recorded a Filipino member of a Korean cult describing his introduction to the group. That is a current member talking.
Youtube link here.Certainly with that cult - www.jmscult.com - recruitment can have nothing to do with any other factors than how well the recruiters tell their lies, flatter and manipulate.
Certainly, in the beginning, the cult seems to offer things that any person would want - to be accepted and valued, and to be part of an organisation doing "wonderful" work.
That cult, and others, do try to replace the member's family, so people from broken or unhappy families, may be more easily lured by that aspect.
