And then you'll get the "My account has been banned by Amazon after misclassifying a single listing" posts.

There are two sides to the problem, and changing criteria for suspension just shifts it to the other side.

Considering the amount of fraudulent reports that already go on with Amazon, this would not be tenable. Remember Amazon Marketplace wants to grow as well. It is also important for big brands to have the ability to create lots of new listings at scale. For example, every year or every fashion season, brands release entire slates of new products. It is important for Amazon to function to allow sellers and agents of brands to be able to create lots of new listings at once. Manual review would greatly delay that process and create a lot of unnecessary frustrations.

A lot of things that one might think of such as "well, whitelist the big brands" or "use enhanced reviews on sensitive, regulated categories" is already built in to Amazon's policies, protocols, and automated systems.

If you want a zero fault option, buy direct from brands. I often do that myself.
