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
Or a bad actor hoping to draw in vulnerable folks online for their scams, like children.
More than one YouTube channel has been attacked by folks pretending to be them in the comments of their videos, scamming their viewers out of money. And no matter how obvious the scam seems, it always seems to catch a few people.
I also know scams will often intentionally use poor grammar or misspell simple things, because they want to catch the kind of person who would overlook those things, like the very naive or the very old, because they’re more likely to get money out of those groups.
Not saying botting on YouTube isn’t a thing, I just don’t think it’s as prevalent as one might initially think.
