Well, the 'flirty fishing' is quite well - known. As I said before, it involved using female members sexually, which is extremely immoral and shows how the cult was willing to use any means to gain new followers.
The isolation of members from their families is another big one. Many people who joined the cult were cut off from their loved ones. They were made to believe that their families were 'evil' or 'worldly' and that only the cult could offer them salvation. This led to a lot of broken families and individuals with psychological trauma.
There were also stories of physical abuse within the cult. Members who didn't conform to the cult leader's demands were beaten and tortured. This created an atmosphere of constant fear, where people lived in dread of making a mistake and facing the wrath of the cult leaders.
