▲ ▼ Online fraud detection systems are broken
Online infrastructure service providers especially the cloud providers ban the customer accounts at whim often due to flawed, outdated fraud detection systems.
There are numerous horror stories from customers on how their accounts were banned for no apparent reason without proper recourse.
There are genuine cases of fraudulent activities happening using the cloud infrastructure, but the current mechanisms used to identify those activities are inefficient and therefore genuine customers who haven't done anything wrong get caught up in it. I presume both the service providers and the customers would like to get this need-gap addressed.
