An instant ban for vendors detected and confirmed to be doing this. Amazon has plenty of ability to deal with this, from a ML detection system to human validation. They just don't want to.
They do, but they just pop up as a different seller under a different name with a different business address and the cycle goes on. That's why all the sellers have weird names and make no effort to drive any sort of brand awareness or loyalty.
So mark a vendor as "new vendor", add mandatory ghost shopping to all product skews (postage returns paid by vendor), funds only clear after product arrives + n days for new accouts, etc to build in security that products sold are legitimate. All you need to do is make cost of standing up a scam more expensive than the real thing.
That's something different though somewhat similar.
All that tech, platforms, manpower and literally all the backend data about it (access patterns, descriptions, sales, back accounts, user agents, IPs, everything) and they can't detect something that's blindingly obvious to anyone paying attention?
Even more than that, they require government IDs and other documentation to set up seller accounts, but at the end of the day it's easy to come up with new straw front people for your scam, with clean papers, addresses, and bank accounts.
Noone at Amazon is looking at the id. If they did it would add 'friction'
Why would they not want to? This is a serious business problem for Amazon, isn't it?
I don't know why they don't want to, but a database query for "\d{2}TB SSD" with a price under $100 is surely not beyond a global top-three AI company with a half-trillion dollars of revenue.
