Note the reviews refer to all different stuff - phone chargers, arm slings, extension cord organisers. What a total shitshow.
A more targeted approach might be to disallow sellers from adding variants to products which are not currently for sale. I suspect that would cut down on most of the abuse.
If you want to deal with this problem rather than channel more of it into a place some of it already goes, it should, because completely different products are added as “sizes” or “colors” of existing products already.
If you add a review fraud control and leave this an escape hatch, well, the results are predictable.
This is an exploit which has been abused for years -- as I understand it, Amazon sellers can list their products as a "variant" of another, often unrelated, product which is no longer available for sale. When they do so, their product inherits all of the reviews from the previous product, and no obvious indication is given that the other variant ever existed (because it's not available).
How can you even expect regular people to know it's a scam? I only vaguely have an indication that £30,99 (the price it gives me) for 2TB seems too good to be true. I work in IT, but I don't spend all days buying portable SSDs so I don't really know what these things cost today, and the "Amazon's choice" label makes it give a false sense of trust ("wow it's really cheap, but maybe just some discount or whatnot? Well, I guess it must be alright because it's Amazon's Choice!")
They could be legit and failed QA in the factory (flaky after all) but they "fell off a truck" on the way to the electronics recycler and ended up for sale. Semi-counterfeit "3rd shift" products that are made off the books on the official line, often with lower or nonexistent QA, are common too.
tl;dr counterfeiting is complicated and just opening it up might not give you a reliable answer
3.0 out of 5 stars Good storage capacity

While the storage capacity is good for the value I would only use this for small files as it corrupted any large video files I had, additionally, the transfer speed was quite slow (especially for USB 3.0) reaching speeds of up to 16mb/s and regularly dropping to 0mb/s, this is not a fault of my pc as other USB 3.0 devices can reach speeds of 80mb/s on my pc.
