Kids these days raised by YouTube comments.
Wouldn't be surprised if your average teenager in 1st world spends more time reading comments than talking (or even texting) with RL friends.
Wouldn't be surprised if that's true for elders as well actually.
I follow a lot of YouTube channels. Some are reviews of favorite shows. Some are fan edits. Some are reaction channels. Some are informative history channels, emphasis on medieval/Tudor. There's a treasure trove of Harry Potter analysis videos. There's a guy who actually tests out some of the ideas in FRPGs to see if they really work (ie. which kind of frying pan makes the best weapon, or how many gold pieces could a D&D fighter realistically carry around while exploring and fighting).
The scam situations, though? Travel channel hosts have been impersonated, and so has one of the reaction channel hosts. They've made a point of telling the viewers, though - if you see me anywhere but here (or on their other usual social media sites), IT'S NOT ME.
Yes, I read comments. Yes, I leave comments. I've had some fun conversations on a few of those sites. There have been some frustrating arguments.
And yes, some of these channels are monetized and some people send money during livestreams (I never have).
About the most suspicious things I've seen, though, are on FB. It's getting easier to spot the plagiarists and the AI, and there are groups I belong to where even mentioning AI will result in a permaban.
