I may be wrong, but my guess is this is an attempt to weed out the 4,217 positive reviews tomorrows' newly introduced gadget gets on the day of introduction, all posted by bots from different IP addresses in the first few hours the product has existed. Amazon, et. al. are going to be, if not already, rife with this nonsense.
Personally, I tend to read the 1-star reviews first, as they are least likely to be fake, although often over represented since moderately satisfied folks are usually more sanguine, and don't bellow their feelings as often.
Unfortunately, a lot of reviewers will see a change in the nature of their revenue stream. Hopefully, the market will adjust. I remember when I was working in a small HI-Fi shop back in the 70's and one key reason I worked there was to get 50% off retail from almost every line we represented. Working for a couple of bucks an hour plus commission, that was a major incentive, and items I purchased were chosen after extensive in-store comparitive demo'ing of the exact item. There were also "spiffs" where extra commission was paid on occasion to highlight certain items, but if a product wasn't a good one, it wouldn't be in our store in any case.
I still have most of those purchases which were based on weeks, not hours of evaluation. The market moves too fast today to allow such luxuries except on a forum like this where the discussions are only "tainted" by the difference in hearing ability and personal taste, as it should be. If you love Wilson, you may not choose a set of Mag's for your second system, but that does not mean either are "bad", just different, and perhaps each is best for the listening environment it serves in. As always, YMMV.
