These are just the fake reviews we know about. Now imagine everything we don't know about. Political comments on reddit. Political comments on youtube and facebook. User reviews on metacritic for video games and movies.
Basically, you can't trust any comments online unless you personally know the person who wrote them, and know they are trustworthy. The whole idea that you can put stock in anonymous online conversations, and for instance say "the data shows that x percent of twitter users support this," or "are against this," needs to be completely re-examined. The internet is the most powerful tool for propaganda to ever exist, especially when you can pass one party's propaganda off as something that hundreds of thousands, or millions, of independent people agree with, just with some bot algorithms or "AI" algorithms. Heck, we don't even know what type of algorithms have been developed in secret.
I mean, people post their political opinions online, or their opinions about anything, as if their voice matters, but just one algorithm can create 100,000 fake account accounts, aka fake "voices," to say the exact opposite as you. The first one completely negates your post, and then the next 99,999 turn your voice into a fringe minority viewpoint next to the "consensus" of 99,999 "people."
Until we all realize how many, possibly a majority(?), of the comments we read online are fake, people will continue to get fooled by this.
