I sometimes watch Facebook reels, and found that there are sooo many videos which don't make any sense. Even the comments people just write what they want to write which are not related to the videos at all ? What is this phenomenon?

Facebookのreels、全然意味がわからない動画が多い? コメント見てもみなさん適当に好きなこと書いてて、動画へのコメントじゃなかったりするw なんなの、この現象w
