|So it seems you could show one product and show ratings and reviews for a completely different product underneath it.|
I've been noticing a lot of these on Amazon now-a-days and I'm not sure what's the loophole and how they manage to achieve it.
Look at this product -
The product is a wireless earbud. And if you scroll down, you can clearly see the reviews are for a Sony headphone case. Completely different.
Or this - https://www.amazon.com/littlejian-Headphones-Earphones-Microphone-Compatible/dp/B07SRP7F1X/
It's an headphone, but the ratings and reviews are for a Facial steamer!
There are several examples. I got fooled nearly when the reviews are for a headphone, and the product is also a headphone, except they are completely different products.. I'm not even sure what to categorize this as.
I tried searching for this but couldn't find any references to this. If you have faced this / know if this has been covered already, please share the relevant links.
