Having been responsible for standing up insider risk management protocols and systems in financial services, this usually occurs at high level executive/senior roles and it's part of your employment agreement that data will be collected and evaluated for the purpose (in a similar sense to an overzealous, continuous background check).

I don't support blackmail in any form, full stop. I do want to know if you're going to embezzle millions of dollars before you do, as do shareholders or customers (if you're managing assets) of the organization.
