Happened to me when I saw a book on the US site, I wasn’t able to see all reviews, but there was a button to sort-of “apply” to get approved for seeing all of them.
It took five days, then I got this email.
Interestingly, they’re not doing this on the European site, you can still see all reviews there.
There has been tons of products with fake reviews for over a decade as well by now.
I remember back when Amazon was a source for trustworthy products in the earlier days. Then they let the shady sellers in. Then they hid the country the product ships from. Then tolerated blatantly fake reviews. And now they’re hiding the reviews they don’t like? Why would anyone want to purchase anything from that service at that point?
If I want something I have to order online nowadays I’ll go out of my way to find an online store that isn’t Amazon. And if it’s something I can’t find anywhere else, I’d go on AliExpress. It’s likely going to be a junk product but at least it’s priced accordingly. Amazon products nowadays are just AliExpress products with a 5000% markup.
