They should get a year in jail for each card that they stole.
Whatever prison they go to should do an investigation and match the hackers up with other prisoners that had their identity stolen at some point for a cellmate.
I would give them a small cut for each card they stole....they might last for a good thousand cuts or so....
That sounds fair to me. Sure, 160 million years is a lot but they'll be up for parole in only 80 million.
