The unlikely places where people spend money
People may try to cover their tracks when making money in the dark web, but they will likely let the guard down when spending money.
There are things that everyone does, specially if they have money: like traveling or buying luxury items. This approach allows also to study where users spend. This includes the supply chain of online businesses. For instance, a similar network to the one shown in Figure 19 can be constructed to map where a particular site does acquisition, where they spend their advertisement money, who benefits from advertising in those sites, and so on. This analysis extends to the inventory level, to answer questions such as what products (and conversations) generate the largest money flows, and, what are the emerging demand for particular items and information products-- those typically serve as leading indicators.
