Historically, what kind of leakers tend to be prosecuted? And by whom? Do you have any reason to believe your tool will buck these trends?
Maybe the world would be better of if the person who leaked the Minton Report, showing that the Trafigura corporation was knowingly dumping toxic waste [1], was deanonymized and "took responsibility" for their actions?
Forgive me if I'm being harsh, but you knew perfectly well that "insiders" is an irrelevant non-answer.
