One of the major issues is counterfeit baby products, specifically sleep products. In the US, sleep spaces for babies are highly regulated. The terms “bassinet, crib, and playard” are terms that can only be used for products that pass rigorous ASTM testing. If something doesn’t complete that testing then they are not allowed to use one of those terms in ads or on their manual. This is why you’ll see many products listed as “loungers” because they’re not safe for sleep. There are hundreds of products online that are horribly made and steal manuals of actual approved products. Amazon is notified (groups I’m in notify them) and they don’t care. There are also products that aren’t knock-off versions of things but just flat out lie and say a product is safe for sleep when it isn’t and will use one of the protected terms - which makes the sale of them illegal.
