People steal account numbers all the time, and then sell them in bundles on the internet. The buyer usually will test the stolen accounts with $1 purchases somewhere on line. If they go through, then they light 'em up.
Happened to us a couple of years ago.. Person hit us for a buck, and then tried to buy a full blown Mac for around four grand. Our bank's fraud protection software shut 'em right down.
FWIW, My debit card got shut down in mexico all the time when I was living there. I would draw a couple hundred bucks at an ATM every week or so, and sometimes they would shut it right down seeing the transaction coming from Mexico. Then i had the pleasure of talking to someone in India about my American bank account being used in Mexico. That was always a fun 45 minutes..
