Yes but one Reddit comment has a lot more weight right now because of the ease of astroturfing, so it doesn’t need to be a Bot. Someone posts a Swiss Army knife and someone else might say, “I love my Swiss Army Knife that my grandfather left me. Oddly enough my aunt thought it was lost and bought me a knockoff from Amazon and it actually works better than my grandfather’s knife.”
Then someone replies saying “what was the brand?”
Then the person replies with a picture of the knife with the lettering in tatters saying “QUINIPO” or one of those Chinese brand names.
And there is a market for buying up old Reddit accounts for that. People cultivate karma on Reddit accounts posting about cats and memes and then sell them to brands looking to appear authentic.
For some subreddits like r/BuyItForLife, it's not about the number of upvotes. Some people just gravitates toward old fashion goods.
