Seems like a waste of time?...to me anyway. Here's why: If I'm gonna buy something of such a monetary value that I want to be sure the product is worthy of purchase, I'm going to take the time to read customer reviews. That alone would give me sufficient information as to whether the product is acceptable & if a plurality of the reviews authentic. Some people include pictures & videos in their review. Other people make annoyingly common spelling, diction, style & grammar mistakes that could almost guarantee their authenticity... or lack thereof. For instance, I just purchased the DJI Osmo Mobile 3. Being over $100.00, I'm going to research the price and reviews from many sources & platforms. Pricewaiter, Amazon, Google shopping, Tiger Direct, NewEgg, Ebay, Youtube. Use service widgets like Honey & Wikibuy. Organize the results a few ways, like price + shipping from lowest to highest, etc. I initially found the combo pack for $139.00. After about 15 min. of searching, I found what would be the best price of $108.00. In short, the normal -to me - course of research makes it clear whether a product is a good buy, rather than sussing out fake reviews. Unless I'm not fully understanding the purpose for which you want the app/prog.
