German police take down 'world's largest darknet marketplace'
I get how these market places are used for digital goods (malware, credit cards), but I don’t understand how people can trade physical goods on those. If they have to exchange products, they must either meet in person or use the mail, either is trackable by the authorities. I see how the seller can protect himself for local transactions. He could leave the goods hidden somewhere and tell the buyer where to go. But the buyer has to be exposed 100% of the time.
