It must be a variant of the brushing scam but instead of sending junk to verified addresses from data leaks, they're just grabbing new users with too good to be true offers and switching up the products then writing fake reviews when it's delivered. Looks like the kind of tat some IG "influencer" would try to hawk to their followers on some drop shipping site.
That or simply bait and switch and long drawn out refund/returns system that runs past the point you can do a charge back.
