Back to Dervish's question of cults adopting kids.
Yes and in Victoria, Australia. 60 Minutes produced a story on 25 July 2004 exposing an infamous woman by the name of Anne Hamilton-Byrne who ran her own cult and abducted newly born babies from hospitals with the help of cult member doctors and nurses.
This is one of the most hidieus cult stories I have come across - please read the overview to the story. The transcript can be purchased:
Children were hidden in the mountains and lived in shocking conditions. They were brought up to believe that Anne was the re-encarnated Jesus Christ. They were starved of food and received both psychological and physical torture. Her cult has been running for over 30 years.
