They asked for feedback regarding spotting fake online reviews, and got it.

14. "They go into long-winded explanations why the product is so much better than other, pretty much identical, products sold under different brand names."
22. The username has more than 3 numbers at the end.
27. "My favorite way to double check a fake review is to highlight a peculiar phrasing in the review and do a google search for it.
Disclaimer: I'm on the board of Consumer Reports, due to their extraordinary integrity, and that as I get old, appliance reviews get exciting.
