While some may indeed be looking for a payday more than justice, please don't get carried away with the generizations that essentially blame victims.
There are Childhood sexual abuse survivors, both male and female who did not come forward at the time because their abusers (often a family member, family 'friend', or an authority figure like a priest) had them convinced that even if anyone believed them no one would care enough to protect them. Worse some abusers threaten not only their victims but other beings-- family or animals.
The man who raped my sisters and probably many others in the children's home they were in for some 3-4 years lured the youngest (she was preschool age in early 1940's) of them to the furnace room with a litter of young kittens. Blood got on her long johns and he burned them in furnace. She knew she'd get in trouble for not having them anymore, but he threatened to throw the kittens in the furnace if she told anyone the truth.
She has never acknowledged the assault out loud, nor did she in a memoir excerpt she wrote and sent me. But she shared all those other details over the years. I suspect she has a disassociative block against remembering the act itself---many survivors do for many years or their whole lives. But she focused all her pain and anger on the fact she got punished for 'losing' her long johns when she didn't actually. And it affected her deeply. Including always seeking to place blame (even natural occurrences that are inconvenient) others for things before someone blames her.
