There is a lot of info at The Best of... WTS and Sexual Abuse of Children
When confronted ekders the abusers will deny. The accuser (most often still a child) must produce 2 witnesses.
Now how absurd is that? Sexual abuse rarely, happens in front of other people. Abusers rely on the fact that it will boil down to an adult's word over that of a child.
Since there are no witneeses to the abuse the elders accept the word of the adult saying they can do nothing. Now th be clear about this - elders cannot do anything as leaders of the congregation. According to their rules the issue disappears. The accused is declared innocent - within the congregation. That is the extent of their "spiritual help"
Now a couple of other things come into play here.
The WTS has pretty clear rules about not bringing shame on "Jehovah's" name or the WTS. If the accused is not a JW then the elders might be more willing to tell the victim they should go to the authorities. But if the accused is a JW going outside the cong with accusations of sexual abuse would cross that line of bringing shame on the org.
The victim winds up with a gag order within the cong. Elders tell the victim that repeating the accusations to others would "cause divisions" which could result in facing a judicial committee.
If the victim tells others about the accusations the elders again could call that JD and accuse them of gossip and spreading lies (because thier investigation resulted in an "innocent" finding)
So the victim gets no help because he or she can't go outside the congregation because they would be bringiont shame on the WTS/JWs. And the victim can't tell anyone within the cong because he or she will be meeting in the back room with a group of elders saying they need to shut up or risk getting tossed out.
As crazy as all this sounds this is how it works and a number of people here have goine through it
