The late Corey Haim (the famous child actor from Lost Boys) was one of the victims to this phenomenon. According to his best friend Corey Feldman, Haim was sodomized by a "powerful" guy in the Hollywood, when he was 16 years old (at the sets of the film Lucas). Haim became a bisexual and drug addict, finally dying at the age of 38 from drug addiction.
I remember Feldman talking about that in several interviews - he wrote a book that goes into a lot of this but I've never read it. Supposedly from what he said, ol' Meathead - Rob Reiner - is the big pedophile he was talking about, remember Feldman was in Stand By Me and Reiner directed that film.
I remember seeing Lucas as a kid, never knew that. Just disgusting:
Haim confided in his new friend that on the set of the 1986 film “Lucas,” “an adult male convinced him that it was perfectly normal for older men and younger boys in the business to have sexual relations, that it was what all the guys do. So they walked off to a secluded area between two trailers . . . and Haim allowed himself to be sodomized.”
Haim then followed this shocking tale with a question.
“So,” he said to his new bestie. “I guess we should play around like that, too?”
