In a bid to stop false feedback, Amazon has placed a limit on the number of reviews a week shoppers can leave on the site. People can now write only five reviews a week of items not bought via the online store. The change is Amazon’s latest step in its battle to ensure users trust its listings.

Earlier this year, Amazon began suing sellers for buying fake reviews and then Imposed tougher restrictions on companies that offered free products in return for customer’s ratings. Users can still review as many items as they like if the goods are purchased via the website. (28th November 16)
