Kappy hasn't admitted to what he's done and nothing he says can be trusted. He says he doxxed nobody and that what he did is worse than doxxing. He said from 1-10 being bad, it's a 10. That being said, here's what I think.
Last year he asked SRA victims to share their stories with him for a documentary he was going to make. He never made the documentary. I think he used that info to try and extort powerful people and perhaps got caught and is trying to save face. Or he doxxed the victims and now the cabal knows who they are. Another theory is he was gaining info from high level white hats, and shared them with the black hats.
