They could do a similarity diff. If you switch content from towels to solar panels I bet they could get pretty good signal just from text comparison. “This looks like a different product. Different products must use their own SKU. If you believe this is an error, appeal here.”

ChatGPT can definitely work this out.

Even a simple Levenshtein distance would do the trick for most of these product switches.

I don't get they don't crack down on the product switcheroo scam [0] - it seems like a trivial problem to solve. I've reported items to them before and they don't care. [0] this product for example, loads of the reviews are for something totally different - https://www.amazon.co.uk/WERPOWER-Windscreen-Invisible-Winds...

How is it trivial to solve? They either need to prevent sellers from modifying product pages (which would be a disaster because any mistakes could no longer be fixed without losing all reviews) or gate it behind human intervention(slow) /algorithm (complex). There's nothing trivial about the issue.

It shouldn’t take a particularly strong classifier to detect that two descriptions are for entirely different products. And product reviews are a major part of Amazon’s business, so improving the situation should be easily within Amazon’s budget.

Also, noticing and penalizing sellers who do this shouldn’t be particularly hard.

The craziest scam I saw on Amazon was ordering an expensive GPU > people change the card's backplate and return a cheaper/broken one. Unsuspecting regular Joe will order the returned GPU ("open box deal!") and they get a fake one. And now you have to fight against the Amazon customer service too. It's incredible. Amazon is basically a "premium" Wish/Aliexpress nowadays. Might as well I order from China becuase I at l…

I like getting products I order online delivered overnight. And return them for free by dropping off at local UPS with my money back in less than 48 hours. Can Wish/Aliexpress do the same?

It doesn't even need an LLM, I'm pretty sure regular NLP methods would be able to handle it, given how dramatic the product changes are.

Exactly, or at least that could flag it for manual review. It has to be a deliberately unsolved problem.

Couple of fairly simple things they could do to at least help somewhat: * Put reviews for current listing at the top of the reviews (currently default sort seems to be a vague "Top reviews", but can be changed to "most recent" which presumably accomplishes this. Vast majority never change defaults though) * Clearly mark any review that is for a previous version of the listing, and provide a link to view the listing a…

I don't think this will work well. Minor updates to listings would trigger all of these actions far too often to make them standard and ignored.

I hate to say it but I think some type of heuristics would be needed here.

1. Has the title significantly changed. 2. Has the price significantly changed. 3. Are the search keywords that were finding the old listing significantly different than those finding the new listing. 4. Have average ratings and common words in reviews changed? (Especially rarer words that match the new and old listing respectively)

If some of these start to look suspicious then I think you can start to apply your mitigations. You can probably even scale them by how sure you are. For example reviews are always downranked by age and significant changes to the listing amplify this effect, you can add the same weight to the start rating.

And of course the real way to prevent this is to flip the incentive. Add human review and a warning before killing the account. Make it so that the cost of being caught negates the benefit of doing this.
