Thanks for this useful info! Can you explain why someone would get 100% positive and 100% negative on quality when the consumer could not have yet received their product? Nothing else is rated yet. My son just started a business and the product he's advertising is getting a lot of negative comments on the ads based on similar products they've gotten from other sellers in the past. He's chosen to ignore those comments since they're not for his product. Could FB be paying attention to these random individual comments? Any light you can shine on this FB black hole would be much appreciated!
