"such are so tracable"

You truly believe that? What's "so traceable" is the fact X card number was used at Y to purchase Z goods/services.

Generally legit carders, don't buy stuff and ship it to their home. They don't use the numbers to make a fake card and show up in person without some disguise from the possible cameras at ATMs, or otherwise.

They can take advantage of small businesses that process card transactions with the illegal bait-buys...appear as an overseas manufacturing company in a country that has high costs for items you sell, say Steel or things of that nature that a simple UPS package won't suffice.
Buy $7k worth of goods from them, and since it's going overseas, and that small business may not be familiar with using international freight brokers. The buyer mentions a company they use for international freight to "get to the Netherlands" or wherever. Continue the social engineering to convince the small company that part or even all of the freight needs to be paid upfront to that front freight company. Thief pays with stolen credit card, but already has your $2k in freight, or will same time frame. Your CC processor finds out the transaction is fraudulent via some means, such as the cardholder calling. The stolen funds are charged back, and taken from small business, scummy buyer has your $2k freight that you paid sitting in whatever front company account they have and they disappear. You may think that seems implausible, but from consulting we've seen it more than a few times.

Same way ppl don't ever understand how people actually click spam "V1agra cheappp~~~~" emails, and still do (or used to more often).

The card companies monitoring doesn't catch all of it, some victims are simply too lazy to monitor their statements more than once per month when they get the email or in the mail "new statement".

Also have seen those that purchase dumps of info, and so forth specifically target card numbers of areas hit by natural disasters. The reason...well your odds are a lot higher than the victims card you used during that crisis isn't going to or can't check their statements. Katrina was a case of this, where people by the time they cared or could find a card statement or internet, and back when fraud monitoring was far worse than now. It'd take weeks or months before that transaction would come back fraud from the victim.

It's brutal, but carders and thief's don't have that empathy trait.
