Seller-side here. Amazon combine my author page, with that of A.A. Milne. Some of my products show up under the deceased author, some of his under mine. Reviews for one particular product are combined.

My seller ID is separate, my last name is also Milne, but my first is James.

He wrote a book called "The Red House Mystery", I wrote an homage to it because I am related to the man, called "Red House". Different products, with different ISBNs.

Combined reviews. [0]

That's not exactly a fair process for customers - and no, I can't get them uncombined. I've been trying for years. But if the seller can't get rid of something completely misleading, that seems to have been caused by a very badly automated process, then there are processes at Amazon that cause problems.

I've only ever left one bad review on Amazon. Chopsticks, they came bound together with some sticky tape. Sticky tape left a very sticky area just where your hands go that I was unable to get off despite a lot of effort scrubbing, washing, and so on. I left a polite constructive review saying they were good chopsticks but watch out for this stickiness issue. My review was declined by Amazon on the grounds it didn't meet their "community guidelines" (without elaborating further on which rule I'd supposedly broken).

They absolutely do, it's personally happened to me. My review was rejected because I simply listed what items were included in the box, one of them being a card that offered a bribe for a positive review.

Every review I left for Amazon products (Amazon EU) got rejected until it was diluted into nothing. The explanation was always vague, listing a dozen possible reasons, none of which fit what I wrote.

On non-Amazon products it's a coin toss for negative reviews. Many are published, some are not. Can't explain why.

Google is not better, negative reviews I leave on Maps are published very selectively. Maybe big-tech found a way to monetize this too. I know sites like Yelp are more or less an extortion business where you pay to get negative reviews wiped.

Neither does Temu. They're misrepresenting what Temu does, at least in my experience.

If you choose a star rating below five, Temu asks if you'd like to request a refund or seek other assistance. The one time I said yes -- it was a keyboard where a shift key wouldn't trigger consistently at the peculiar angle that my typing style hit it at -- it immediately gave me a 100% refund and said just keep it.

But I've left other low-star rating without trouble. The refund/assistance suggestion is an entirely optional sidetrack.

I've never (to my knowledge) had a review on Amazon rejected, and I've left very some negative reviews, including when I received counterfeit items.

I always thought the review scams on Amazon were more driven by the third-party sellers doing stuff like listing takeover, astroturfing reviews, bribing customers for good reviews, etc., but maybe I'm wrong. I have personally received multiple offers from third-party sellers of incentives to leave good reviews.

I bought a pcie wifi card on amazon.

It came with a "get $20 if you leave a 5 star review" card in it.

I took a picture and included it in my review.

Amazon declined to publish it.

So, they do shady shit like this for sure.

Either you've never used amazon or you are lying in bad faith.
