Beyond just the pedophilia, his (Epstein) operation was largely one of socialising, and securing (probably coerced) introductions from people he helped facilitate and now held blackmail over.

e.g. using blackmail material on a Bill Gates to secure an introduction to another wealthy and influential individual, offering them a “massage” and then producing kompromat at a later date to bring them into his circle.

Now don’t get me wrong, everyone who found themselves in this position was a willing participant, not a victim - but I can understand how so many oligarchs eventually found their way into his little black book.
