This episode really brought me back to my old job screening e-commerce customer reviews. If you can believe it, the promotion-triggered reviews in this doc are more effortful than the average for promotion reviews; most of the ones I read were just "you know this product, right? It's good." (I once had a block of dozens of Pine-Sol reviews that were basically all "it's Pine-Sol, you know what it is and what it does, but they gave me some free stuff so here's my review: buy it if you like Pine-Sol.")
