The fame reviews are mostly easy to spot (although of xours sits impossible to know which ones you didn't spot...) - eg that they have photos is for me a clear indicator of fakes. But even if you actually recognise them, it wastes your lifetime and makes it more difficult to find authentically good products - in particular in the areas with high competition where you have fake positive and fake negative reviews (paid for by competitors), eg robot vacuums.
