You can, but they have an algo checking for their no-nos. You have to dance around certain words that the algo might think mean a problem with the seller, shipper, or delivery.

I see a ton of reviews that get around it somehow. I guess it only pertains to real people.

I hate the listings with hundreds or thousands of reviews for an entirely different product. I report them all the time but have never seen anything done.

At my old apartment I used to get tons of unsolicited crap from Amazon and when I complained they told me it was 'gifts'. I asked how to return it but they couldn't tell me because it was all scammers. I asked if I could block 'gifts' and they told me to be happy getting free, Chinese, plastic junk.
