Legimately don't remember the last time I bought a product on Amazon that I found for the first time on the site that didn't come with one of these. Kitchen gear, USB Cables, Knickknacks, Clothing, "Wanna leave a review for a 15 dollar rebate?".
I also got a free umbrella on a freelance site once for leaving a review for said umbrella. I didn't understand what the motivation was for the sellers and I really only found out after I had gotten the umbrella what the TOS Violation was, so I immediately mailed the appropriate Amazon email to report the violation. Naturally literally nothing happened. Umbrella has been nice enough though ¯\_(ツ)_/¯.
TIL they operate their own DTC sites (of course). Will give those a try next time.
~2016 I worked for an Amazon Marketplace seller – avoiding the banhammer was our biggest priority, having been banned once because a unisex fragrance (perfume) we sold "smelled too masculine" and therefore the customer told Amazon it was counterfeit.
Given we often had inventory available in FBA (Fulfillment by Amazon) and not in our own warehouse, we often fulfilled eBay orders via FBA.
I've been out of the business for awhile, I think the rules around this from eBay's end have changed. Regardless, it's common for sellers to use 3PL (third-party warehousing and fulfillment) services, FBA or otherwise.
Every time I read about businesses getting banned on FAANG listings due to SEO tricks, I get extremely concerned about the other side: how easy it is for a third party to get someone innocent banned.
Somehow they got my email address and keep sending me vaguely threatening untraceable emails to "reconsider" my review in exchange for gift cards.
Super shady. Glad Amazon is finally doing something
