I have a family member the grew up as JW. She was raped by a member of the church, but because she did not have a witness, she was kicked out. They have a rule where a man and woman cannot be alone together, even in a office or car etc. Since she didn't have a witness, she broke that rule. Since she didn't have a witness it was considered to have never happened and her saying it did was her spreading lies against church members.

Since they kinda force you to not socialize with anyone, even family outside of the cult, she basically lost all her friends and family that she had any contact with growing up.
