I know of a guy, but his scenario was quite unique. I was working for an energy company who shall remain nameless, but who's internal IT was a tangle of external consultants milking the place for millions, and ineffective/underserved full time staff who couldn't run a query on a database without a change control committee of consultants milking them for yet more cash. Anyway, this guy was the go to guy for gas custom…
That sounds highly illegal.
