I don't believe either Lanksy or Capone were personally worth anywhere near those figures posted in that thread. The $750 million taken from customers through the internet and phone cramming scams, run by the Gambino family's Locascio crew, is well documented but it's not like all of that money went into their pockets. The prosecution alleged something like $40 million was kicked up to the Gambino leadership as tribute after the guys actually involved in the scams took their cut. They all made a lot of money, and were able to pay huge fines, but it was much less than that total $750 million figure.
