Yandex in particular has a system where it would dynamically adjust the price to prevent that sort of thing happening. When many people want to order a taxi to the same place, it gets really expensive, really fast. Uber does that too. This normally works well, but I feel like this hack bypassed the normal ordering system entirely and just sent bogus orders straight to drivers.

New customers are allowed to pay in cash to the driver, which makes it effectively anonymous. Nothing was at stake.
