But this title made me think of the fraudulent practices by the buyers. It's a well-known problem in China, a small percentage of scammers will always try to abuse the system to its knees, as a result, vendors are forced to end their favorable policies (e.g. RMA), effectively causing a Denial-of-Service of convenient and high-quality services to the majority, legitimate customers. It is not limited to vendors, customer, but also widespread in the public services and financial sector. I think this is called a "low-trust society".
I believe having a system based on trust can be a viable solution. Unfortunately, this type proposal has been intentionally scaled-up by the government, leads to the upcoming "social credit system", based on mass surveillance.
And I think nowadays this approach as a solution is a dead-end, any similar system proposed by a government or a corporation will eventually become a mass surveillance system. Even the """relatively""" harmless financial credit system seems to go out of control, and a more concerning issue is that, unlike the Anti-Encryption Bill, a trust-based system can be legitimate, and solves real, severe problems, making it harder to argue against mass surveillance systems in disguise of trust and credit.
