In my experience the chat on chess.com harbors a similar demographic to that of most video games. You'd think that chess would attract a more mature player base, but nope.
The only time I've observed people in real life acting like people in video games is at a chess tournament. Constantly trash-talking until they lose, then accusations of cheating. You certainly don't see this type at all (or most) chess events; I think the lack of entry free drew them out into the open.
At my local library the loudest people aren't those on their phones or laptops, but the chess players. It really surprised me considering chess can be played completely non-verbally other than calling "check". Every time I'm there, they constantly argue (most of the time it's because someone wants to take back a move), trash talk to get on each others nerves, yell across the table to other players in games, and talk loudly as if they were in a park. On one hand I think it's great that the library provides a community space and lets people use their chess sets, but on the other hand as someone who goes there for quiet, it's very irritating. (I wish they had a game room or something where they could go wild) Once upon a time libraries had mythical status as a place of silence, to the point where people would shush each other for the smallest noises... I actually stopped going to that library because of noise issues and in general because of its size and limited seating.
Didn't expect Chess.com and YouTube to have a crossover of users? Surprised there isn't active moderation on a site this size.
