You seem unaware of the history around the Pinkertons.
Short story is that this was a private agency that openly offered services like the ones performed by the Ebay contractors, all the way to the point of directed murder, and did across decades, within living memory.
Nowadays, such services are offered mainly in war zones, by companies like what used to be called Blackwater, later Xi, run by Erik Prince, brother of Betsy de Vos. So there is still a market served, just a bit more circumspectly. But nobody who hires them goes to jail, and they don't either.
