Ali and eBay have been at this for years. I've got a X to sell for £100. I can also sell Y, which costs £50. I'll advertise with the main selling price of Y and the main picture/description of X ... Profit! Most people are selling X for £75, and a real bargain would be £50, so it doesn't seem 'too good to be true' that a seller would have a X for £50, on a good day. It isn't Ali that's doing it, they're just complicit in not closing the loophole that's being exploited by sellers. Caveat emptor.
