It's frustrating because it's like keeping a family secret. There is no evidence and will never be. I often meet young people who speculate on what happened and want some bullshit like innocent until proven guilty, or statistics, or police reports. It is.. sort of like your uncle confessing to an affair. You can't give evidence that it's happening without some betrayal and nothing good will come out of it. They know how to keep it legal. All you do is hurt your own credibility. The victims will often refuse to believe you and want more proof anyway. But so far, all of them meet with karma.
My advice: don't do it. It's incredibly demotivating and while you often don't need motivation to get something done, demotivation will keep you from getting anything real done. Projects like these bleed talent and are full of unpleasant people. And the ones who play with corruption and lies are also likely to lie to you and exploit you.
