YouTube comment sections are weirdly positive always. It could be a video of some horrible crime and the comments will be about how great the channel is and encouraging the channel to keep making more videos. When j visit actual fan pages anywhere else online there are always a mix of opinions. But youtube is constantly full of obsequious people
The comments in the early years of YouTube were entirely filled with childish flame wars. I honestly think the only reason that this didn’t kill the site is because they started purging the negativity. Nowadays I’m sure it’s a lot easier for them with the developmental upgrades in bots.
