I've had two fairly detailed, not low-effort, reviews not approved for publication on Amazon.co.uk recently. After the first I swore I'd never bother again (it was pretty high-effort to be honest, relatively) but something got the better of me.
Neither time has there been any indication of what the problem is (I guessed the first one was my reference to a 'knob', as in for turning, which the product had - but couldn't find any such similar Scunthorpe in the second) and even if they did give you some idea, they invite you to start again from scratch - not edit it, it's not saved, not even your photos. I'd love to see click-through metrics on that, does anyone bother?
