I did a quick search on this particular topic and didn’t find anything specific or related to this “NEW Amazon’s reviews policies.” Link below.

Amazon has specific policies that are meant to protect the authenticity of Customer Reviews, and we ask you to comply with these policies and report any violations you might notice. We have provided links to our policy pages below. Note that Amazon has a zero-tolerance policy towards any customer reviews violations. If we detect any attempts to manipulate customer reviews, we take immediate actions that include, but are not limited to:

• Immediate and permanent withdrawal of the seller’s selling privileges on Amazon and withholding of funds.

• The removal of all the product’s reviews and preventing the product from receiving future reviews or ratings.

• Permanent delisting of the product from Amazon.

• Legal action against the seller, including lawsuits and referral to civil and criminal enforcement authorities.

• Disclosing the seller’s name and other related information publicly.

Violations to Customer Reviews policies include, but are not limited to, these actions:

• A seller posts a review of their own product or their competitor’s product.

• A seller offers a third party a financial reward, discount, free products, or other compensation in exchange for a review on their product or their competitor’s product. This includes using services that sell customer reviews, websites, or social media groups.

• A seller offers to provide a refund or reimbursement after the buyer writes a review (including reimbursement via a non-Amazon payment method). This could be done via buyer-seller messaging on Amazon or directly contacting customers or using 3rd party services, websites, or social media groups.

• A seller uses a third-party service that offers free or discounted products tied to a review (for example, a review club that requires customers to register their Amazon public profile so that sellers can monitor their reviews).

• A family member or employee of the seller posts a review of the seller’s product or a competitor’s product.

• A seller asks a reviewer to change or remove their review. They might also offer a refund or other compensation to a reviewer in exchange for doing so.

• A seller diverts negative reviews to be sent to them or to a different feedback mechanism while positive reviews are sent to Amazon.

• A seller creates a variation relationship between products with the aim of manipulating reviews and boosting a product’s star rating via review aggregation.

• A seller inserts a request for a positive Amazon review or an incentive in exchange for a review into product packaging or shipping box.

• A seller uses a customer account to write or change a review on his or his competitor’s product.

I sure hope this applies to ALL marketplaces and indeed holds it’s weight regarding the above “actions.” – Best of luck and Happy selling!
