Yeah from Theil's books he leads to it. In fraud, people and computers combined are pretty powerful. So the company just creates tools to help a human find issues. An analyst would come into work and see a massive dashboard, then notice contractors pay has doubled since last week, then drill into "contractor irregularities", then see one user perform 200 jobs in the last hour, then click on the user's geo information and realize it comes from an IP address in Florida, then they click on "open ports", the machine has port 80 open (hacked). They resolve the problem by creating a new rule, "IF user job count > X, per hour || port 80 open, pause payment && report". etc etc. They just keep adjusting these rules to keep fraud rates down. It isn't ever 0, but they keep modifying the rules to minimize OVER and UNDER reports. It is comically basic.
