Fraud happened on this network. I learned this at the "Musée des Arts et Métiers" in Paris. From this Wikipedia article [0] : The network was reserved for government use, but an early case of wire fraud occurred in 1834 when two bankers, François and Joseph Blanc, bribed the operators at a station near Tours on the line between Paris and Bordeaux to pass Paris stock exchange information to an accomplice in Bordeaux.
