You're making some leaps logic here here. If someone's outed as a pedophile, everyone who's friends with him should be assumed to be a pedophile? Surely not, given that pedophilia is considered taboo, we'd expect them to hide it, and therefore at least some friends might not be in the know. That's not to say there's no conspirators, but "he was friends with a pedophile therefore he's a pedophile too" is just guilt by association. What you need to prove is that he knew, or ought to have known that his friend was a pedophile. A conviction works decently for this, because it's presumably public knowledge, although even that's questionable because most people don't do a background check on people they met. In the case of Epstien he also hired reputation management firms to suppress his conviction from showing up in the results, which weakens the case even more.
