As tptacek says, I don't view reporting like this as "doxxing." As the series hopefully shows, Le Roux was a hugely newsworthy figure for many different reasons, so reporting his background and how he got there is part of understanding where he is now. As for being nervous, many of the major players in the story are in US custody, and perhaps somewhat counterintuitively a lot of people involved want to tell their part of the story. If they have beefs, they are typically with each other not with me. I do try to be careful, though.
Original author of the story here... Just to add that 1. yes, the reporting on Le Roux's childhood is more tentative based on a family source (well backed up by docs and images sent to me). But the fact that the same Le Roux created E4M which formed the basis of TrueCrypt is something I think I've established definitively, company and site registration trails show it very firmly (and PLR himself admits it in court, but that comes in a later part of my story). And 2. for the _very_ interested, TC is actually just a small part of Le Roux's story, of which we've released three of seven parts (weekly on Thursdays). I know, TL;DR, it's a lot.
