So you funded mailpile, and you want them to have your money. Seems cut and dry... but it's not. If it's a credit card, you might not pay your debt. That's a risk borne by Visa and MC. If it turns out to be a stolen card, all parties on the receiving end might be obligated to return the money. If Mailpile is honest, they will comply, but if Mailpile is responsible for the fraudulent payment, they just successfully laundered some stolen credit into their bank account. Maybe they can't get the whole $100k in cash, so it's not realistic since AML says they can't have more than 10k at a time. I would be very suspicious if I was mailpile's bank and they came in to close the account tomorrow. But, I don't think that's how AML works.
