“We’ve known for over a decade that people come to Reddit to talk about the products they love – take r/BuyItForLife for example, a community of over 1.5 million redditors who have been sharing recommendations and advice about their lifelong, must-have purchases since 2011. These updates will uplevel the search-and-discover experience for both brands and our users by tapping into our differentiated value as a hub for actionable conversation”
So paid manipulation of the sub that was designed to inform users of genuinely good quality products, this probably will be the case for every major subreddit about any consumer product.
