Yep, I understood your point, and it is good to know that this presumed social score system is not particularly strict, but I asked out of curiosity on the reasons why you have such a high (IMHO) return rate.

As well another question is what is actually doing (or not doing) Amazon about the USB sticks/drives issues, the return rate of that should be something like 90% assuming that 5% of buyers fail to realize that the size is much smaller and - still say - another 5% buys them "for later use" and do not test them on arrival.

In a traditional brick and mortar store there would be someone monitoring the return rate for defects on any item for sale as - besides the loss of perceived reliability - there would be objectives costs for handling the returns.
