BTW, what do you think will happen when people find out that their neighbor is secretly a pretty wealthy criminal? Attempts of theft, robbery and extortion have happened in the wake of such announcements.
There was even a case where somebody attempted to impersonate an intelligence officer and try to force a recently doxxed cyber criminal to bribe them.
Who knows, but I'm also not sure how you avoid that situation. Presumably, to be "doxxed" like this, there's substantive evidence he is actually the criminal. Strikes me as just one more downside of being a successful (but now identified) extortionist.
