"I’ve used Amazon for years, probably spend between $5k to $8k a year and have never encountered any of the problems you describe. " That sounds hard to believe. I encounter co-mingling of reviews all the time. And to be clear, I'm a huge fan of Amazon and buy almost everything except groceries through them, but the review quality is pretty inconsistent on many items. Co-mingling is the biggest and most obvious issue I have faced, but I'm sure fake or fraudulent reviews are another big issue that's not immediately obvious to reviewers.
