That would be explicitly illegal, and anybody who tried it would properly be arrested and imprisoned.
I doubt that there are any "whistleblowers" outside of the Islamic world who would be willing to go to those lengths for anybody.
I'd think that the courts would protect a whistleblower who violates personal data privacy laws in order to expose someone who is perpetuating a fraud under protection from those laws.
Data privacy laws cannot shield a person who is running for president under false pretenses, while jailing the person who exposed the fraud.
