What's a company secret you can share now that you no longer work there?

I recall watching a video about the nature of how things are stored at Amazon warehouses - basically if there are multiple sellers offering the same item it all goes in the same bin. Even if you are providing a genuine product, there's a very good chance one of the other sellers is not, and that counterfeit gets sent out attached to your seller ID. Then you get a complaint for selling a counterfeit item someone else provided.

Then when that seller is caught and booted, they just register another trademark with 5-10 random characters and do it again. This is causing a massive headache for the US Trademark Office as well.

Having worked for Amazon across multiple facilities. This is not true or at least wasn’t. When stowing everything seemed pretty random for spots. Seemed to be where ever there was space. But the items themselves when not sold directly by Amazon use a different set of numbers than the B00 number I think it is an FBA (fulfilled by Amazon) number.
That being said, just going to the bathroom was enough to tank the rate for day and have to play catch-up. Lunches reset this.
In one facility they caught two people in a Gaylord having some relations. Same facility they found a used sex toy that had biological material.

I bought a pepper grinder called the Pepper Cannon. Yes, its wonderfully overengineered and costs a fortune. But it's made in the USA, and they've been pretty open with their startup process for making it.

Few months ago I was browsing across amazon and lo and behold, some pepper grinders that look identical to the pepper cannon came up. They were all cheaper knockoffs, selling for a fraction of the cost, and outright stealing PCs industrial design. I didn't buy one, as I don't need one and didn't really care enough to test if the mechanism was the same as the one I bought, but I did drop a line to the pepper cannon guys so they can try to get em delisted

Now I want a Pepper Cannon. Would you recommend getting it, before I ruin my hype by looking up the price or what is actually is? :D
- Its really great if you like pepper. It puts out an absolute ton of it, and you'll find yourself going through way more black pepper than you thought you ever could. And the grind settings are unrivaled; you can get tiny little faerie dusts of pepper, all the way up to big honkin flakes that work great on a steak. Whenever I'm doing a brisket or similar on the smoker, its great to have on hand
  Its milled out of a single billet of aluminum, the grinding mechanism js custom built, and the whole thing just screams quality.
  And you pay for it. They're around $200
  There's also a salt cannon, if you want the same sort of thing but built for salt. I got it because I like the matching pair, but you don't strictly need it; salt is salt, regardless of where it was ground.

  Interresting. Looks like I have one of those knock-offs, I suppose we got it in a supermarket or something :D But I realize that paying for quality in something that includes any kind of razors will make a notable difference, so I guess the price can be justified.

I think there's a lot, yet I also don't doubt you.

'Course, at this point so much of the stuff is the same randomly-generated-brand-name Chinese shit as EBay and Aliexpress have anyway that it doesn't really matter anymore most of the time.

This is not a secret

It's what happens when it turns into a marketplace where 3rd party vendors can sell to.

I always thought there's exactly 0 counterfeit/fake items at amazon, so ... 0 times million ... phew...

I wrote a review about a counterfeit item I received. They never approved that one. I haven't bought cologne from them since.

I bought a bicycle light set (front and rear) a few years ago. They work fine (in fact, I still use the headlight; the rear still works, but it was replaced by a radar light), and I wrote a review. More recently, I was looking back through my purchases, and I came across the review I'd written, but the lights they were now selling on that page were a completely different design than the ones I had.
I edited my review to note that the current lights didn't match the ones I had, not that it'll do any good with a million other reviews of those lights. I know Amazon doesn't really care, but I very often see "There is a newer version of this item available here" links, so I'm surprised that this was possible.
- I’ve gone through reviews where it’s not even the same product. 🤬

Exactly why I only buy from Amazon when I can't find it after searching elsewhere for a while.

they dont care one bit to fix the problem

Who is they? Warehouse workers? Because without getting into too many details, I know someone fairly high up at Amazon corporate, and if I recall correctly her colleague runs a whole...divison? I don't know, largish multi-person unit...and their whole job is addressing the counterfeit problem. I think it's just really hard to do.

Amazon has a policy of binning items with the same UPC together, regardless of the source. What this means is if you buy a valid product and any vendor who is part of their warehouse storage system sells counterfeits, then there is a chance of you getting a counterfeit part, regardless of who you buy from. This reduces the number of locations required for a given item. It just requires that you trust your vendors to not counterfeit. If they were kept separate you could easily see who is selling counterfeits, but it would require more space.
So Amazon has traded the ability to sell parts from verifiable vendors for short-term profits. At this point in the game, your best assumption is if there is any knock-off company selling the product you wish to buy you have no way of knowing it it's legitimate or counterfeit. This is currently diluting their brand and will ultimately impact their sales, if not their profits.
- Amazon makes something like 80% of their profit off of Amazon web services. They have no reason to give the tiniest crap about any physical product they will ever sell ever again.
  
  Yes, and I recall an interview with a bank over a decade ago where someone asked why they have service charges when all it seems to do is piss off their customers. He tried to dismiss the significance of service charges by pointing out that they only represent 15% of their revenue. And yet they still have service charges.
  The reason both these things happen is because profits are put above everything else, no matter how small they are or how irritating they are to the customer. Rest assured, Amazon is no different. They will happily engage in practices that encourage counterfeit sales until such time as they have indications that dealing with it will improve their bottom line. Even 1% will be worth it, let alone 20.
Well the easiest solution is to go back to having Amazon be the seller of products on Amazon, but we all one that ship sailed.
But if the problem is shared bin storage, the solution isn't free, but it's also not as expensive as lots of buyer confidence:
Tag every item with a QR code indicating its source when it comes into the distribution center. Use that code to identify the bad actors when there are returns and ban them.
"But what about products not shipped by Amazon?"
In that case, you know who sold and shipped the product, and if they can't get their shit together they shouldn't be allowed to work with Amazon.
It's not hard to do it, its hard to do it and make the same amount of money...

One of the major issues is counterfeit baby products, specifically sleep products. In the US, sleep spaces for babies are highly regulated. The terms “bassinet, crib, and playard” are terms that can only be used for products that pass rigorous ASTM testing. If something doesn’t complete that testing then they are not allowed to use one of those terms in ads or on their manual. This is why you’ll see many products listed as “loungers” because they’re not safe for sleep. There are hundreds of products online that are horribly made and steal manuals of actual approved products. Amazon is notified (groups I’m in notify them) and they don’t care. There are also products that aren’t knock-off versions of things but just flat out lie and say a product is safe for sleep when it isn’t and will use one of the protected terms - which makes the sale of them illegal.

Random advice: if the market for your product is already lousy with scams without amazon, dont by it on amazon!
