Drop shippers who arbitrage between major and minor ecommerce platforms need to maintain their listings, re-price things, etc. They don't care if the AI gets it wrong sometimes as long as they more than make back the cost of deploying it.

So now imagine ten thousand of these jerks telling their AI of choice "hey go scrape everything you can and re-list it for 10% more". That's a lot of load on the platforms at both ends for listings that are unlikely to generate many sales.
