Where I found what information to be exact?

As mentioned above, pertaining to this:

I believe that the owner or some other SE'er will do a warranty request on the product and give the same serial number

I'll rephrase my question. What gives you the Impression that the owner or some SE'r will In fact do a warranty claim?

Because there’s methods out there for SE’ers to use a serial number when doing a request for replacement of the product. Many well known forums and discord servers are sharing a method for UE. Moreover, the owner may do a warranty claim longer down the line when it becomes defective and what happen when the owner show a valid receipt/invoice of the package? Or many se’ers use the same serial number? Wouldn’t that ring any bells on the company?
