From the companies perspective they have lots of data to analyze. I am not a statistician but I suspect that people who game the system in any way that we can think of will show up at the top of the dataset. The two most important metrics are the highest total earners and the users with the highest average charging fee. They get subjected to extra scrutiny. Plot out where they were getting the scooters from, and who used the scooters last, then if it turns out they are being fraudulent just kick them out or modify the processes so that what they do doesn't work. I suspect in the early days it doesn't really matter, since they will want fully charged scooters and a rumour you can make lots of money to incentivize people to join.
